The dodecahedron has 12 regular pentagonal faces, 20 vertices, and 30 edges. Three faces meet at each vertex. The pentagonal faces of this solid are a bit more difficult to deal with than the others. The calculations below are for a dodecahedron of side length s.
The icosahedron has 20 triangular faces. Any icosahedron will have 20T faces, 12 pentamers and 10(T-1) hexamers. The triangulation number can be graphically determined with the following drawing arranged from Caspar and Klug (1963).
