Platonic Solids
The Platonic solids are the only five convex polyhedra whose faces are all the same regular shape, meeting in the same way at every corner: the tetrahedron (4 triangles), the cube (6 squares), the octahedron (8 triangles), the dodecahedron (12 pentagons) and the icosahedron (20 triangles).

4About it
The Platonic solids are the only five convex polyhedra whose faces are all the same regular shape, meeting in the same way at every corner: the tetrahedron (4 triangles), the cube (6 squares), the octahedron (8 triangles), the dodecahedron (12 pentagons) and the icosahedron (20 triangles). They are named after the Greek thinker Plato, and Euclid proved there can be no others.
It starts as a dodecahedron. Tap it to explode its faces apart; tap again to put them back. Pick any of the five solids, and its colors, in the Splash tab. Many game dice come in these shapes. With ✋ Hands-on on, pull the faces off one by one and lay them down; bring each back near its place and it fits back in.
