How many edges does a tetrahedron have
WebApr 9, 2013 · There are 6 edges on a tetrahedron. The triangular base has 3, plus one for each lateral face. 43 edges Wiki User ∙ 2013-04-09 18:21:43 This answer is: Study guides … WebTake a regular tetrahedron of edge one. Also take a square-based pyramid, whose edges are all one (therefore the side faces are equilateral triangles of same size as the faces of the tetrahedron). Glue a face of the tetrahedron to a triangular face of the pyramid so that their edges match up.
