WebApr 25, 2012 · A convex polyhedron is the convex hull of a finite number of points, that is, a polyhedron which lies on one side of the plane of each of its faces. Its interior is a convex body. If the surface of a convex body is a polyhedron, then the corresponding polyhedron is convex. The following convex polyhedra are most important.
Besides the regular and uniform polyhedra, there are some other classes which have regular faces but lower overall symmetry. Convex polyhedra where every face is the same kind of regular polygon may be found among three families: • Triangles: These polyhedra are called deltahedra.
