WebAll triangular-based pyramids, either regular or irregular, have four vertices. Triangular-based pyramids have 6 edges, 3 are along the base and 3 are extending up from the base. If the six edges are of the same length, all the … WebA tetrahedron is a polyhedron with 4 faces, 6 edges, and 4 vertices, in which all the faces are triangles. It is also known as a triangular pyramid whose base is also a triangle. A regular tetrahedron has equilateral triangles, therefore, all its interior angles measure 60°.
