A Platonic solid is a three-dimensional shape that is highly regular. Specifically, a Platonic solid comprises a set of identical polygonal faces, with the same number of faces meeting at each vertex. There are only five such solids, which are: 1. **Tetrahedron** - 4 triangular faces 2. **Cube (Hexahedron)** - 6 square faces 3. **Octahedron** - 8 triangular faces 4.
