A tetrahedron which is a triangular based pyramid has 4 vertices, 4 faces and 6 edges
A triangular pyramid, or tetrahedron, has 4 vertices and 6 edges.
A triangular based pyramid which is a tetrahedron has 4 faces, 6 edges and 4 vertices
A square pyramid has five vertices whereas a triangular pyramid (tetrahedron) has four.
A pyramid, whose base is a polygon with n sides, has n+1 vertices. Thus a triangular pyramid (tetrahedron) has 4 vertices, a quadrilateral (square or rectangular) pyramid has 5 vertices; etc.
A tetrahedron is a triangular pyramid. It has six edges, four faces and four vertices.
The number of vertices on a solid pyramid will depend on its base as for example if it is a triangular based pyramid (tetrahedron) then it will have 4 vertices, 6 edges and 4 faces.
