Shape W (a triangular - based pyramid) has a triangular base and three triangular lateral faces, but the base may not be congruent to the lateral faces. Shape X has different - shaped faces. Shape Y (a square - based pyramid) has a square base and four triangular lateral faces, and the base is not congruent to the lateral faces.
