Archimedes, a scientist from Ancient Greece, discovered thirteen types of polyhedra, now called Archimedean solids, which are also referred to as semi-regular polyhedra.

Each of them is limited by different types of regular polygons where the polyhedral angles and identical polygons are equal. Furthermore, the same number of equal faces meet at each vertex. In the same order, each of these solids can be inscribed into a sphere.

All these thirteen names make your head spin when you see them for the first time. However, it is possible to sort things out, understand and remember them.
