A triangular-based pyramid, also called a tetrahedron, has no parallel faces, but has 4 faces, 6 edges and 4 vertices
A square pyramid, or square-based pyramid, has 5 faces and 8 edges. One face forms the square base, and there are four triangular faces.
A square pyramid has 1 more face than a tetrahedron. A tetrahedron has 4 faces (equilateral triangles), while a square pyramid has 5 faces (4 triangles and 1 square base). Therefore, the square pyramid has one additional face compared to the tetrahedron.
Its base has 2 pairs of opposite parallel edges and it has 5 faces, 8 edges and 5 vertices.
