What are the new discoveries … WebBut from this description, it becomes immediately obvious that two of the three faces of the small tetrahedron are coplanar with two of the triangular faces of the square pyramid, thus there are only 5 distinct faces to this polyhedron. Explanatory figure taken from the MathWorld link above: Here we see that the coplanarity is evident. Share Cite
