A dodecahedron is a three-dimensional geometric shape that has twelve flat faces, each of which is a regular pentagon. It is one of the five Platonic solids, which are characterized by having identical faces, edges, and angles. The dodecahedron has 20 vertices and 30 edges, making it a fascinating object in the study of geometry. In addition to its mathematical significance, the dodecahedron appears in various fields, including art and architecture. It can be found in polyhedral dice used in tabletop games, as well as in crystal structures in chemistry. Its unique shape also inspires designs in modern furniture and decor.
