- Each face is made of a regular polygon
- All the corners of the shape look the same
- The shape is neither a platonic solid, nor a prism, nor an antiprism.
Depending on the way there are counted, there are thirteen or fifteen such shapes. Of two of these shapes, there are two versions, which cannot be made congruent using rotation. The Archimedean solids are named after the Ancient Greek mathematician Archimedes, who probably discovered them in the 3rd century BC. The writings of Archimedes have been lost, but Pappus of Alexandria summarized them in the 4th century. During the Renaissance, artists and mathematicians valued pure forms and rediscovered all of these forms. Johannes Kepler probably completed this search around 1620.
Constructing an Archimedean solid takes at least two different polygons.
Properties[change | change source]
- Archimedean solids are made of regular polygons, therefore all edges have the same length.
- All Archimedean solids can be produced from Platonic solids, by "cutting the edges" of the platonic solid.
- The type of polygons meting at a corner ("vertex") characterizes both the archimedean and platonic solid
Relationship with Platonic solids[change | change source]
Platonic solids can be turned into Archimedean solids by following a series of rules for their construction.
