What's an Archimedean Solid?

In geometry, an Archimedean solid is one of the 13 solids first enumerated by Archimedes. They are the convex uniform polyhedra composed of regular polygons meeting in identical vertices, excluding the five Platonic solids and excluding the prisms and antiprisms.

What makes an Archimedean solid?

[ är′kə-mē′dē-ən, -mĭ-dē′- ] A polyhedron whose faces are regular polygons and whose angles are all congruent. The faces may all be of the same type, in which case the solid is a regular polyhedron, or may be of different types.

What is a Platonic solid in geometry?

Platonic solid, any of the five geometric solids whose faces are all identical, regular polygons meeting at the same three-dimensional angles. Also known as the five regular polyhedra, they consist of the tetrahedron (or pyramid), cube, octahedron, dodecahedron, and icosahedron.
