What are 2D and 3D shapes?
In geometry, a 2D shape can be defined as a flat plane figure or a shape that has two dimensions – length and width.
Two-dimensional or 2D shapes do not have any thickness and can be measured in only two faces.
If the 2D shape has only straight sides, we call it Polygon.
If the 2D shape has only straight sides, we call it Polygon.

In geometry, a three-dimensional shape can be defined 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 shape.
