WebPolyhedron Definition. A three-dimensional shape with flat polygonal faces, straight edges, and sharp corners or vertices is called a polyhedron. Common examples are cubes, prisms, pyramids. However, cones, and … WebSep 19, 2024 · You can prove every polyhedron has a face with either 3, 4 or 5 sides as follows. If all faces are hexagonal or greater, than 2 E ≥ 6 F. This follows by the handshaking lemma, applied to the "dual graph" of the polyhedron; every face has six or more sides, so the sum of the degrees, which is equal to 2 E, is at least 6 F.
