In this article we’re going to look at 2D shapes and 3D shapes. We shall also explore the names and properties of 2d and 3d shapes. In mathematics especially the area of shape such as trigonometry and scales we use shapes all the time therefore it is important to get a general idea of what popular shapes are available.

2D shapes

2D shapes are the easier shapes to draw, these can be drawn very easily on a piece of paper. You can think of 2D shapes as an outline for 3D shapes. The following shows some of the popular 2d shapes that you will encounter.

2D shapes and 3D shapes-01


2D shapes and 3D shapes-02

A pentagon is commonly described as the 5 sided figure/shape. The shape has 5 sides and 5 corners as you can see from above.


2D shapes and 3D shapes-03

A triangle is a 3 sided shape. This shape has 3 sides and 3 corners as it’s properties.


2D shapes and 3D shapes-04

A square has 4 sides and 4 corners. All sides in a square also has 4 corners. These 4 corners are right angle which form 90 degrees angle.


2D shapes and 3D shapes-14

The circle is a round shape with only one side and no corners.


2D shapes and 3D shapes-05

A rectangle is a 4 sided shape similarly to a square except all the sides are not equal. A rectangle has 2 short equal sides and long equal sides. All the corners are right angle which forms 90 degree angles.


2D shapes and 3D shapes-06

A hexagon is a 6 sided shape which has 6 corners as shown above.

3D shapes

3D/3 dimensional shapes are solid shapes. These are everyday objects that we come across each day. The following shows some of the common 3D shapes.

2D shapes and 3D shapes-08

A cube has 6 flat faces which are squares with equal sides. All sides of a cube are equal.


2D shapes and 3D shapes-09

A cone has a curved face and a flat face. The flat face is the circle which you can see on the shape above.


2D shapes and 3D shapes-15

The sphere pronounced “sfeer” has just one curved face.

Triangular Prism

2D shapes and 3D shapes-10

The above is the triangular prism. This 3D shape is made up of flat triangles and rectangles.


2D shapes and 3D shapes-11

The cuboid is made up of 6 flat & faces which may be squares or rectangles.


2D shapes and 3D shapes-12

The cylinder shown above has curved face and flat curves which are circles.


2D shapes and 3D shapes-13

A pyramid has flat face triangles and squares.
