A 2D shape is a flat shape that has only two dimensions - length and width, with no thickness or depth, that is the reason why it is called a two-dimensional shape . For example, a sheet of paper is two-dimensional in shape. It consists of a length and a width but does not have any depth or height. Some common 2D shapes are squares, rectangles, triangles, circles, and hexagons. Let us learn more about 2D geometric shapes , the difference between 2D and 3D shapes, along with some 2D shapes examples on this page.

What are 2D Shapes?

In geometry, 2D shapes (2 dimensional shapes) can be defined as plane figures that are completely flat and have only two dimensions - length and width. They do not have any thickness and can be measured only by the two dimensions. In comparison to these, a 3D (three-dimensional) shape has three dimensions - length, width, and height. For example, a dice is three-dimensional because it consists of a length, a width, and a height. Some common 3D shapes are cuboids, cones, pyramids, and cylinders.

2D Shapes Definition

A polygon is a 2 dimensional shape made up of straight line segments which are connected with each other, thus giving it a closed shape. A circle, square, rectangle, and triangle are some examples of two-dimensional shapes and these shapes can be drawn on paper. All the 2 dimensional shapes have sides, vertices (corners), and interior angles, except for the circle, which is a curved figure. 2D shapes with at least three straight sides are called polygons and these include triangles, squares, and quadrilaterals . The figure given below shows a list of 2D shapes that we commonly come across.

Types of 2D Shapes - Regular and Irregular 2D Shapes

A 2D shape can be classified as regular or irregular based on the length and the interior angles :

• A 2 dimensional shape (2D shape) is said to be regular if all its sides are equal in length and all its interior angles measure the same.
• A two dimensional shape (2D shape) is irregular if all the sides are of unequal length and all its angles are of unequal measures.

Observe the following figure which shows the difference between regular and irregular two dimensional shapes. It shows a list of 2d shapes.

Difference Between 2D and 3D Shapes

The following table shows a comparison between 2D and 3D shapes.

Properties of 2D Shapes

2-D shapes are flat and can be drawn on a sheet of paper. There are different types of regular and irregular two dimensional shapes like a circle, triangle, square, rectangle, pentagon, and hexagon. Let us learn about a few of them along with their properties.

2D Shapes Names

There are many 2d shapes in geometry. However, a few of them are commonly seen around us and are discussed below. Here is a list of 2D shapes examples along with their properties.

A circle is a closed 2 Dimensional shape made up of a curved line with no corners or edges. Some real-life examples of the circle are coins, wheels, and pizzas. A circle consists of various parts like the radius, diameter, circumference, and so on.

Properties of a Circle

Observe the properties of a circle to identify it as a two-dimensional shape.

• Circles are completely round and made up of a single curved line.
• The circumference is the length of the boundary of the circle.
• The radius is the distance from the center of the circle to the boundary of the circle.
• The diameter is a line segment that goes straight across the circle, through the center. It is the longest possible line that can be drawn inside a circle and is twice the length of the radius.

Observe the following figure to see the different parts of a circle.

A triangle is a 2 dimensional shape with three sides and three vertices (corners).

Properties of a Triangle

Observe the properties of a triangle to identify it as a two dimensional shape.

• A triangle is a closed shape with 3 sides, 3 vertices and 3 angles.
• It is a polygon whose interior angles add up to 180°.

Some real-life examples of a triangle are traffic signs, pyramids, and nachos. The following figure shows the sides and vertices of a triangle.

A square is a 2 dimensional shape with four equal sides and each angle is equal to 90˚. Some of the real-life examples of a square are: a loaf of bread and a chessboard.

Properties of a Square

Observe the properties of the given square PQSR to identify it as a 2D shape.

• All four sides are equal, i.e., side PQ = QS = RS = PR
• Side PQ is parallel to RS.
• Side PR is parallel to QS.
• All four internal angles measure 90 ̊.

A rectangle is a 2D shape with four sides in which the opposite sides are equal and parallel, and all the four angles measure 90 ̊. Some of the real-life examples of a rectangle are table tops, blackboards, cardboard, etc.

Properties of a Rectangle

Observe the properties of the given rectangle ABCD to identify it as a 2D shape.

• Side AB = DC
• Side AD = BC
• Side AB is parallel to DC.
• Side AD is parallel to BC.
• All four angles measure 90 ̊.

Area and Perimeter of 2D Shapes

The area of a 2D shape is the space enclosed within it. The perimeter of a 2D shape is the total length of its boundary. The following table shows the formulas that are used to calculate the area and perimeter of a few common 2D shapes:

Important Notes

Here are a few important notes that should be remembered while studying 2D shapes.

• Every 2D shape can be measured by its width and length.
• All the 2D shapes are completely flat.

2d Shapes Real Life Examples

A few real-life examples of 2d shapes are given below:

• A currency note which has the shape of a rectangle
• A chess board that has the shape of a square.
• A cookie in the shape of a circle.
• A honeycomb with little hexagons in it.

2D Shapes Examples

Example 1: Does a rectangle come under the category of 2D shapes? The length of a rectangle is 32 m and the width is 20 m. Find the perimeter of this rectangle.

Solution : Yes, a rectangle comes under the category of 2D shapes. The length of the given rectangle = 32 m; width = 20 m

We know that the perimeter of a rectangle = 2 (length + width)

P = 2 (32 + 20) = 2 (52) = 2 × 52 = 104 m

Therefore, the perimeter of the rectangle is 104 m.

Example 2: Does a circle come under 2D shapes? Find the area of a circle whose radius is 6 cm.

Area of the circle = π × r 2

= 3.14 × 6 2

= 3.14 × 36

Therefore, the Area of the circle = 113.04 square cm

Example 3: Identify the 2D shapes from the following. Circle, rectangular box, Rubik's cube, hexagon

Among the given shapes, a circle and a hexagon are 2D shapes because they do not have any thickness or depth. A rectangular box and a Rubik's cube are 3D shapes because they have 3 dimensions, (length, width, and height).

FAQs on 2D Shapes

What are 2d shapes in maths.

A 2D (two-dimensional) shape can be defined as a plane figure that can be drawn on a flat surface. It has only two dimensions - length and width, with no thickness or depth. Some of the basic 2D shapes are rectangle, pentagon, quadrilateral, circle, triangles , square, octagon , and hexagon.

What are 2D Shapes and 3D Shapes?

A flat shape that has two dimensions - length and width, is a 2D shape, whereas, a shape that has three dimensions - length, width, and depth (height) is a 3D shape .

What are the Properties of 2D Shapes?

A 2D shape is a flat shape that can be drawn on a plane surface. As the name suggests, it has only two dimensions of length and width without any thickness. While some 2D shapes have sides and vertices, others are made up of curved lines.

How many 2D Shapes are there?

There are many different kinds of 2D shapes, like the rectangle, pentagon, quadrilateral, circle, triangle, square , octagon and hexagon . These are flat shapes that can be drawn on a flat surface.

How to find the Area of 2D Shapes?

The area of a 2D shape is the space occupied by it. Since there are different kinds of 2D shapes like circles, squares, rectangles, etc., there are different formulas used to find their areas. For example, the area of a circle can be calculated with the help of the formula, Area = πr 2 , where 'r' is the radius of the circle and (pi) π is a constant with a value of 22/7. The area of a square is calculated with the formula, Area = side × side. The area of 2D shapes is expressed in square units.

How to Teach 2D Shapes?

Teaching 2D shapes is easy if the concept is introduced in the early years. First of all, the names of the basic shapes can be made to learn. Then, the students should be asked to identify the names of the shapes from a list of 2d shapes. Another interesting way can be by asking them to spot the shapes around them.

Some commonly seen 2d shapes that can be seen in the house are, the rectangular surface of a notebook (rectangle), the circular shape of a clock (circle), the circular shape of a pizza, a square-shaped window (square)

Is Circle a 2D Shape?

Yes, a circle is a 2D shape because it exists on a plane with no depth. It is a curved shape that has no corners or edges.

Which 2D Shape has 4 Sides?

A quadrilateral is a 2D shape that has four sides. For example, quadrilaterals like squares and rectangles are 2D shapes with 4 sides.

Is Oval 2D or 3D Shape?

Oval is a 2D shape because it exists on a plane and has no depth. It is a curved figure with no edges or corners.

Savvino-storozhevsky monastery and museum.

Zvenigorod's most famous sight is the Savvino-Storozhevsky Monastery, which was founded in 1398 by the monk Savva from the Troitse-Sergieva Lavra, at the invitation and with the support of Prince Yury Dmitrievich of Zvenigorod. Savva was later canonised as St Sabbas (Savva) of Storozhev. The monastery late flourished under the reign of Tsar Alexis, who chose the monastery as his family church and often went on pilgrimage there and made lots of donations to it. Most of the monastery’s buildings date from this time. The monastery is heavily fortified with thick walls and six towers, the most impressive of which is the Krasny Tower which also serves as the eastern entrance. The monastery was closed in 1918 and only reopened in 1995. In 1998 Patriarch Alexius II took part in a service to return the relics of St Sabbas to the monastery. Today the monastery has the status of a stauropegic monastery, which is second in status to a lavra. In addition to being a working monastery, it also holds the Zvenigorod Historical, Architectural and Art Museum.

Belfry and Neighbouring Churches

Located near the main entrance is the monastery's belfry which is perhaps the calling card of the monastery due to its uniqueness. It was built in the 1650s and the St Sergius of Radonezh’s Church was opened on the middle tier in the mid-17th century, although it was originally dedicated to the Trinity. The belfry's 35-tonne Great Bladgovestny Bell fell in 1941 and was only restored and returned in 2003. Attached to the belfry is a large refectory and the Transfiguration Church, both of which were built on the orders of Tsar Alexis in the 1650s.  

To the left of the belfry is another, smaller, refectory which is attached to the Trinity Gate-Church, which was also constructed in the 1650s on the orders of Tsar Alexis who made it his own family church. The church is elaborately decorated with colourful trims and underneath the archway is a beautiful 19th century fresco.

Nativity of Virgin Mary Cathedral

The Nativity of Virgin Mary Cathedral is the oldest building in the monastery and among the oldest buildings in the Moscow Region. It was built between 1404 and 1405 during the lifetime of St Sabbas and using the funds of Prince Yury of Zvenigorod. The white-stone cathedral is a standard four-pillar design with a single golden dome. After the death of St Sabbas he was interred in the cathedral and a new altar dedicated to him was added.

Under the reign of Tsar Alexis the cathedral was decorated with frescoes by Stepan Ryazanets, some of which remain today. Tsar Alexis also presented the cathedral with a five-tier iconostasis, the top row of icons have been preserved.

Tsaritsa's Chambers

The Nativity of Virgin Mary Cathedral is located between the Tsaritsa's Chambers of the left and the Palace of Tsar Alexis on the right. The Tsaritsa's Chambers were built in the mid-17th century for the wife of Tsar Alexey - Tsaritsa Maria Ilinichna Miloskavskaya. The design of the building is influenced by the ancient Russian architectural style. Is prettier than the Tsar's chambers opposite, being red in colour with elaborately decorated window frames and entrance.

At present the Tsaritsa's Chambers houses the Zvenigorod Historical, Architectural and Art Museum. Among its displays is an accurate recreation of the interior of a noble lady's chambers including furniture, decorations and a decorated tiled oven, and an exhibition on the history of Zvenigorod and the monastery.

Palace of Tsar Alexis

The Palace of Tsar Alexis was built in the 1650s and is now one of the best surviving examples of non-religious architecture of that era. It was built especially for Tsar Alexis who often visited the monastery on religious pilgrimages. Its most striking feature is its pretty row of nine chimney spouts which resemble towers.

Share All sharing options for: Gagarin Cup Preview: Atlant vs. Salavat Yulaev

Gagarin cup (khl) finals:  atlant moscow oblast vs. salavat yulaev ufa.

Much like the Elitserien Finals, we have a bit of an offense vs. defense match-up in this league Final.  While Ufa let their star top line of Alexander Radulov, Patrick Thoresen and Igor Grigorenko loose on the KHL's Western Conference, Mytischi played a more conservative style, relying on veterans such as former NHLers Jan Bulis, Oleg Petrov, and Jaroslav Obsut.  Just reaching the Finals is a testament to Atlant's disciplined style of play, as they had to knock off much more high profile teams from Yaroslavl and St. Petersburg to do so.  But while they did finish 8th in the league in points, they haven't seen the likes of Ufa, who finished 2nd. 

This series will be a challenge for the underdog, because unlike some of the other KHL teams, Ufa's top players are generally younger and in their prime.  Only Proshkin amongst regular blueliners is over 30, with the work being shared by Kirill Koltsov (28), Andrei Kuteikin (26), Miroslav Blatak (28), Maxim Kondratiev (28) and Dmitri Kalinin (30).  Oleg Tverdovsky hasn't played a lot in the playoffs to date.  Up front, while led by a fairly young top line (24-27), Ufa does have a lot of veterans in support roles:  Vyacheslav Kozlov , Viktor Kozlov , Vladimir Antipov, Sergei Zinovyev and Petr Schastlivy are all over 30.  In fact, the names of all their forwards are familiar to international and NHL fans:  Robert Nilsson , Alexander Svitov, Oleg Saprykin and Jakub Klepis round out the group, all former NHL players.

For Atlant, their veteran roster, with only one of their top six D under the age of 30 (and no top forwards under 30, either), this might be their one shot at a championship.  The team has never won either a Russian Superleague title or the Gagarin Cup, and for players like former NHLer Oleg Petrov, this is probably the last shot at the KHL's top prize.  The team got three extra days rest by winning their Conference Final in six games, and they probably needed to use it.  Atlant does have younger regulars on their roster, but they generally only play a few shifts per game, if that. 

The low event style of game for Atlant probably suits them well, but I don't know how they can manage to keep up against Ufa's speed, skill, and depth.  There is no advantage to be seen in goal, with Erik Ersberg and Konstantin Barulin posting almost identical numbers, and even in terms of recent playoff experience Ufa has them beat.  Luckily for Atlant, Ufa isn't that far away from the Moscow region, so travel shouldn't play a major role. 

I'm predicting that Ufa, winners of the last Superleague title back in 2008, will become the second team to win the Gagarin Cup, and will prevail in five games.  They have a seriously well built team that would honestly compete in the NHL.  They represent the potential of the league, while Atlant represents closer to the reality, as a team full of players who played themselves out of the NHL. 

• Atlant @ Ufa, Friday Apr 8 (3:00 PM CET/10:00 PM EST)
• Atlant @ Ufa, Sunday Apr 10 (1:00 PM CET/8:00 AM EST)
• Ufa @ Atlant, Tuesday Apr 12 (5:30 PM CET/12:30 PM EST)
• Ufa @ Atlant, Thursday Apr 14 (5:30 PM CET/12:30 PM EST)

Games 5-7 are as yet unscheduled, but every second day is the KHL standard, so expect Game 5 to be on Saturday, like an early start.

OpenAI's big event: CTO Mira Murati announces GPT-4o, which gives ChatGPT a better voice and eyes

• OpenAI's "Spring Update" revealed new updates to ChatGPT.
• OpenAI CTO Mira Murati kicked off the event.
• She announced GPT-4o, its next flagship AI model, with improved voice and vision capabilities.

OpenAI just took the wraps off a big new update to ChatGPT.

Cofounder and CEO Sam Altman had teased "new stuff" coming to ChatGPT and GPT-4 , the AI model that powers its chatbot, and told his followers to tune in Monday at 1 p.m. ET for its "Spring Update" to learn more.

Also ahead of time, Altman ruled that the event would reveal GPT-5 or a new OpenAI search engine, which is reportedly in the works. OpenAI is reportedly planning to eventually take on internet search giant Google with its own AI-powered search product.

But the big news on Monday was OpenAI's new flagship AI model, GPT-4o, which will be free to all users and "can reason across audio, vision, and text in real time." It was CTO Mira Murati who delivered the updates with no appearance on the livestream from Altman.

There were a ton of demos intended to demonstrate the real-time smarts of GPT-4o.

OpenAI researchers showed how the new ChatGPT can quickly translate speech and help with basic linear algebra using its visual capabilities. The use of the tech on school assignments has been a polarizing topic in education since it first launched.

Say hello to GPT-4o, our new flagship model which can reason across audio, vision, and text in real time: https://t.co/MYHZB79UqN Text and image input rolling out today in API and ChatGPT with voice and video in the coming weeks. pic.twitter.com/uuthKZyzYx — OpenAI (@OpenAI) May 13, 2024

OpenAI posted another example to X of how one can interact with the new ChatGPT bot. It resembled a video call, and it got pretty meta.

In the video, ChatGPT takes in the room around it, discerns it's a recording setup, figures it might have something to do with OpenAI since the user is wearing a hoodie, and then gets told that the announcement has to do with the AI — it is the AI. It reacts with a voice that sounds more emotive.

OpenAI also announced the desktop version of ChatGPT, and a new and improved user interface.

In addition to GPT-4o and ChatGPT, OpenAI's other products include its AI-powered image generator DALL-E , its unreleased text-to-video generator Sora , and its GPT app store.

You can catch up on our liveblog of the event below.

That’s a wrap! OpenAI concludes the event without an appearance from Altman.

OpenAI says text and image input for GPT-4o-powered ChatGPT is launching today. Meanwhile, voice and video options will drop in the coming weeks, the company said.

Although Altman didn't step in front of the camera, the CEO posted videos from the audience on X.

He also teases "more stuff to share soon."

GPT-4o can also break down charts

The new AI model can interact with code bases, the OpenAI execs say. The next demo shows it analyzing a chart from some data.

It's a plot of global temperatures. GPT-4o gives some takeaways from what it sees, and CTO Mira Murati asks about the Y axis, which the AI explains.

ChatGPT reads human emotions — with a stumble

For the last live demo of the day, Zoph holds his phone up to his face and asks ChatGPT to tell him how he looks. Initially, it identifies him as a "wooden surface" — a reference to an earlier photo he had shared.

But after a second try, the model gives a better answer.

"It looks like you're feeling pretty happy and cheerful," ChatGPT says, noting the small smile on Zoph's face.

In one of the final tests, ChatGPT becomes a translator

In response to a request from an X user, Murati speaks to ChatGPT in Italian.

In turn, the bot translates her query into English for Zoph and Chen.

"Mike, she wonders if whales could talk, what would they tell us?" she said in English after hearing Murati's Italian.

It's pretty impressive.

The video demo shows how it could help with math homework, including basic linear algebra

OpenAI Research Lead Barret Zoph walks through an equation on a whiteboard (3x+1=4), and ChatGPT gives him hints as he finds the value of x — making it basically a real-time math tutor.

At the beginning, the bot jumped the gun.

"Whoops, I got too excited," it said after it tried to solve the math problem hadn't been uploaded yet.

But it then walked him through each step, recognizing his written work as he tried to solve the equation.

It was able to recognize math symbols, and even a heart.

OpenAI's first demo: Talking to GPT-4o

It's demo time!

The new bot has a voice that sounds like an American female, but no word yet if you can change it.

OpenAI Research Lead Mark Chen pulled out ChatGPT on his phone and asks for advice on giving a live presentation using Voice Mode.

"Mark, you're not a vacuum cleaner," it responds when he hyperventilates, appearing to perceive his nervousness. It then tells him to moderate his breathing.

Some big changes, you can interrupt the AI now, and there shouldn't be the usual 2 or 3-second delay with GPT-4o.

It can also detect emotion, according to OpenAI.

GPT-4o will have improved voice capabilities

Murati emphasizes the necessity of safety with the real-time voice and audio capabilities of the new GPT-4o model.

She says OpenAI is "continuing our iterative deployment to bring all the capabilities to you."

Murati says the big news is a "new flagship model" called GPT-4o.

The new model is called GPT-4o, and Murati says that OpenAI is making a "huge step forward" with ease of use with the new model.

It's free for users, and "allows us to bring GPT-4 class intelligence to our free users," Murati says.

And we're off!

The livestream began with CTO Mira Murati at OpenAI's offices.

OpenAI is going to be announcing 3 things today, she says. "That's it."

For those who want to watch live, you can view the whole event here.

OpenAI will be livestreaming its spring update, which kicks off in less than an hour.

Axel Springer, Business Insider's parent company, has a global deal to allow OpenAI to train its models on its media brands' reporting.
