Polyhedron polyhedra

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. WebRegular polyhedra are often represented with a notation called Schläfli symbols which consist of two numbers between curly braces. The first number is the number of sides on each polygon, and the second is the number of such polygons surrounding each vertex (i.e. corner). For example, {4,3} is the cube because each vertex is surrounded by ...
