When we say "dodecahedron" we often mean "regular dodecahedron" (in other words all faces are the same size and shape), but it doesn't have to be - this is also a dodecahedron, even though all faces are not the same. 12-Sided Dice? Yes! A dodecahedron which has 12 equal faces has an equal chance of landing on any face. The Icosahedron - Dyn The regular icosahedron is one of the five Platonic solids.It is bounded by 20 equilateral triangles, and has 12 vertices and 30 edges. Its dual is the dodecahedron. It can be cut into two pentagonal pyramids and a pentagonal antiprism, or a pentagonal pyramid and a gyroelongated pentagonal pyramid (J11).It can also be cut by two non-parallel planes to produce the metabidiminished icosahedron Icosahedron - an overview | ScienceDirect Topics

In the natural world, the icosahedron is the shape favoured by a number of viruses, including the infamous herpes virus. The icosahedron is the only one of the platonic solids to have a dihedral angle with a magnitude greater than one hundred and twenty degrees. Like the octahedron, the icosahedron has two different vertex angles.
