To create a tetrahedron, three triangles come together and they meet at a vertex. The point where at least two straight lines come together is the vertex. When analyzing the ordinary convex polyhedra, the tetrahedron is the simplest of all of them. It is also the only one with less than five faces. It is a type of pyramid with triangular faces that come together at a common point and it has a flat polygon base.

A tetrahedron is a shape made out of four triangular faces, and it has a total of six edges. Although each of the four sides of a tetrahedron has three edges, the shape does not have 12 edges, as some of the edges are shared.This figure can also be referred to as a triangular pyramid.
