A tetrahedron, or triangular pyramid, is a polyhedron consisting of 4 triangles between 4 vertices. A tetrahedron splits the euclidean space in two by the plane defined by the first 3 vertices and the positive side being the side that includes the fourth vertex. If a all 4 vertices are coplanar the tetrahedron is considered degenerate. Tetrahedrons only exists in 3 dimensions.
