                  Two-dimensional shapes
                  Plane figures with only two measurements –length and width are called 2-D shapes.
                  For example:












                  Three-dimensional shapes

                  Shapes which can be measured in 3 directions are called three-dimensional shapes. These
                  shapes are also called solid shapes. Length, width, and height (or depth or thickness ) are
                  the three measurements of the three-dimensional shapes.
                  Example :


















                  Solid figures with three measurements –length, width and height are called 3D shapes.

                  Views of 3D-Shapes

                  As the 3-D shapes are solid in nature so they may have a different view from different sides.
















                  When we draw the top view, front view and side view on paper then it will look like this.
