In geometry, a tetrahedron is a polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The tetrahedron is the simplest of all the ordinary convex polyhedra.

In a regular tetrahedron, not only are all its faces the same size and shape but so are all its vertices and edges.
