The more common name for a tetrahedron is a triangular pyramid. It is a three-dimensional geometric shape composed of four triangular faces, with three of those faces meeting at each vertex. Tetrahedrons are one of the simplest forms of polyhedra and have applications in various fields, including chemistry and architecture.

The platonic solids are: a tetrahedron, a cube, an octahedron, dodecahedron and icosahedron. A pyramid has a base with triangles attached to it with a common vertex. The platonic solid that is a pyramid is a tetrahedron (a triangular based pyramid).
