A platonic solid is a polyhedron all
of whose faces are congruent regular polygons, and where the
same number of faces meet at every vertex. A polyhedron is a
solid figure bounded by plane polygons or faces. There are only
five platonic solids.
The Greek philosopher Plato described
the solids in detail in his book "Timaeus" and assigned the
items to the Platonic conception of the world, hence today they
are well-known under the name "Platonic Solids."
Euler's polyhedron theorem: F + V = E
where F, V, E are the number of faces, vertices, and edges in
