2.27.8 6th Seminar

Draw vertex-edge graphs for the five polyhedra that are platonic solids:

tetrahedron (4)

hexahedron (6)

octahedron (8)

dodecahedron (12)

icosahedron (20)

The vertex-edge graphs should be isomorphic with the solids themselves in terms of their characteristics (vertices, edges and faces).  To keep track of these, you can use applet linked here.

Remember that in a vertex-edge graph the outside space counts as a face.
