Polyhedrons are three-dimensional geometric shapes with flat polygonal faces, straight edges, and vertices. They are characterized by their number of faces, vertices, and edges, which are related by Euler's formula: ( V - E + F = 2 ), where ( V ) is vertices, ( E ) is edges, and ( F ) is faces. Polyhedrons can be classified into regular (Platonic solids, where all faces are identical) and irregular types. Their faces can vary in shape, but they are always formed by connecting edges at vertices.

Crystalline solids have a particular geometric organization of their atoms. Amorphous solids do not.
Yes, the Platonic solids (excluding the sphere which does not have vertices).
A dodecahedron is a three-dimensional geometric shape that has 12 faces. Each face is a regular pentagon, and it is one of the five Platonic solids. In total, a dodecahedron has 20 vertices and 30 edges.
