WebRegular Polyhedra. There are indeed only five regular (convex) polyhedra. And the fact was known to the ancient Greeks. Another term for the regular (convex) polyhedra is Platonic bodies. The fact is very well known and there is a great variety of different proofs to choose from. I like the one based on the Euler's formula.

WebA three-dimensional shape whose faces are polygons is known as a polyhedron. This term comes from the Greek words poly, which means "many," and hedron, which means "face." So, quite literally, a polyhedron is a three-dimensional object with many faces. The faces of a cube are squares. The faces of a rectangular prism are rectangles.
