Question:
Answers:A tetrahedron (plural: tetrahedra) is a polyhedron composed of four triangular faces, three of which meet at each vertex. A regular tetrahedron is one in which the four triangles are regular, or "equilateral," and is one of the Platonic solids. The tetrahedron is one kind of pyramid; the second most common type. Other pyramids have a flat base, and triangular faces above it, but the base can be of any polygonal shape, not just square or triangular.  So your question depends on the shape of the base of the pyramid. In the case of a triangular base, there are four faces (including the base as a face), four vertices, and 6 edges. For a square base pyramid, there are four faces (I didn't include the base as a face), 5 vertices, and 8 edges.
