A 5-sided 2-dimensional figure is a pentagon and a 5-sided 3-dimensional shape is a pentahedron.
A nine(9) sided two-dimensional figure/shape.
The net of a 2 dimensional shape can be folded into a 3 dimensional shape
A geometric net of a 3-dimensional object is a single two-dimensional figure that can be folded into the 3-d shape.
Any 2-dimensional shape can be folded to form a 3-d shape. For example, any work of origami.
A net for the 3D shape.
A net is a two dimensional pattern that can be cut out and folded to make a 3-dimensional [solid] shape. A 2-dimensional shape, such as a square, does not have a net!
