Archimedean solids, like Platonic solids, must be convex figures, but they are not exactly the same as Platonic solids. Archimedean Solids are the convex polyhedra that have a similar arrangement of nonintersecting regular convex polygons of two or more different types arranged in the same way about each vertex with all the edges the same length. Archimedean solids are convex figures that can be made up of two or more types of regular polygons. All edge lengths of the polygons must be equal, and all of the vertices must be identical, meaning the polygons that meet at each vertex do so in the same way.
Here are some examples of Archimedean Solids:
