Convex polyhedron whose faces are composed of at least two different types of regular convex polygons.

The condition of being composed of two different types of polygons distinguishes Archimedean solids from Platonic solids.

Archimedean solids are also called **semi-regular convex polyhedra**.

There are 13 Archimedean solids:

### Historical note

The Archimedean solids were named after the Greek mathematician Archimedes, who described them in one of his works (now lost). Through their study of pure forms, artists and mathematicians of the Renaissance rediscovered the Archimedean solids. This study was completed around 1619 by Johannes Kepler.
