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 ... WebIn geometry, a spherical polyhedron or spherical tiling is a tiling of the sphere in which the surface is divided or partitioned by great arcs into bounded regions called spherical polygons.Much of the theory of symmetrical polyhedra is most conveniently derived in this way..
