WebLet P be a convex polyhedron with V vertices, E edges, and F faces. then . V - E + F = 2. We will start the proof by choosing a point C inside P. Since P is convex, the line segment joining C to any point inside the polyhedron P, or on P itself, lies entirely within P. WebPOLYHEDRA AND POLYTOPES (a) (b) Figure 4.1: (a) An H-polyhedron. (b) A V-polytope Obviously, polyhedra and polytopes are convex and closed (in E). Since the notions of H-polytope and V-polytope are equivalent (see Theorem 4.7), we often use the simpler locution polytope. Examples of an H-polyhedron and of a V-polytope are shown in Figure 4.1.
