Example: 1 Mark

A shape that has only two dimensions (such as width and height) and no thickness is known as 2-D shape. In 2-D shapes, the sides are made of straight and curved lines.
Example: squares, circles, triangles


A 3-D shape is a solid which encloses volume and has length, breadth and height. 3-D shapes have four properties that set them apart from 2-D shapes: faces, vertices, edges and volume.
Example: sphere, cylinder, cube
