A polyhedron whose faces are identical regular polygons. All side lengths are equal, and all angles are equal.

Such as this Dodecahedron (notice that each face is an identical regular pentagon).

There are five convex regular polyhedra, known as the Platonic Solids.

And there are also four regular "star polyhedra", known as Kepler-Poinsot solids.
