WebA platonic solid is a 3D shape where each face is the same as a regular polygon and has the same number of faces meeting at each vertex. A regular, convex polyhedron with identical faces made up of congruent convex regular polygons is called a platonic solid. There are 5 different kinds of solids that are named by the number of faces that each solid has. 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.
