WebA regular polyhedron is a polyhedron whose symmetry group acts transitively on its flags. A regular polyhedron is highly symmetrical, ... This simply reflects that the surface is a topological 2-sphere, and so is also true, for example, of any polyhedron which is star-shaped with respect to some interior point. WebOnly five regular polyhedrons are possible. These are listed in the table on the right. There are two particular spheres associated with any regular polyhedron. First is the circum-sphere This is the sphere which fits around the outside of the polyhedron so as to touch all its vertices (or corners). Its diameter is given here as the circum ...
