Answer 2

http://en.wikipedia.org/wiki/Regular_polyhedron
A regular polyhedron is a polyhedron whose faces are congruent regular polygons which are assembled in the same way around each vertex. A regular polyhedron is highly symmetrical, being all of edge-transitive, vertex-transitive and face-transitive - i.e. it is transitive on its flags. This last alone is a sufficient definition.

Each vertex has sides next to it, one triangle, and two rectangles. These are congruent (equal) for each vertex.
