## What Is A Two Dimensional (2D) Shape?

A two-dimensional shape can be described as a flat plane figure or a shape that has length and width but no depth. Two-dimensional or 2-D shapes do not have any thickness and can be measured in only two faces.

Examples of two-dimensional shapes:

- Circle
- Square
- Triangle
- Rhombus
- Rectangle
- Pentagon
- Octagon etc

### Facts About 2D Shapes

- A 2D shape has two dimensions, that is, Length and Breadth whereas curved shapes such as circles and ellipse have radii.
- 2D shapes are used to give simple view of an object.
- In mathematics and physics, a 2D figure is plotted on two axes, that is, the X- and Y-axes.
- In 2D shapes, all the edges are clearly visible.
- 2D shapes are easy to explain due to the visibility of all its edges.
- Detailing 2D shapes is easy.
- It is easy to draw 2D shapes.
- Area, perimeter can be found for these shapes.
- Examples of 2D shapes include: Circle, Square, Rectangle or any other polygon etc.

## What Is A Three Dimensional (3D) Shape?

A three-dimensional shape can be described as a solid figure or an object or shape that has three dimensions-length, width and height. Unlike two-dimensional shapes, three-dimensional shapes have thickness or depth. The attributes of a three-dimensional figure are faces, edges and vertices. The three dimensions compose the edges of a 3D geometric s shape.

Examples of three-dimensional shapes:

- Cube
- Rectangular prism
- Sphere
- Cone
- Triangular prism
- Cylinder
- Tube

### Facts About 3D Shapes

- A 3D shape has three dimensions, that is, Length, Breadth and Height or Depth.
- 3D shapes are used to give architectural view of an object.
- In mathematics and Physics, a 3D figure is plotted on three axes, that is, the X-, Y- and Z-axes.
- In 3D shapes, not all edges are clearly visible; some of the edges are hidden.
- In 3D shapes, only outer dimensions can be explained.
- Detailing becomes difficult in 3D shapes.
- 3D shapes are complex in drawing.
- We can calculate their volume, CSA, LSA or TSA.
- Examples of 3D shapes include: Cylinder, Prism, Tube, Cuboid etc.
