An hexagonal based pyramid would fit the given description
A triangle based prism.
A triangle based prismoid and a quadrilateral based pyramid.A prismoid is like a prism except that its bases (the triangular faces) need not be congruent nor parallel.
A tetrahedron is a triangular based pyramid that has 4 equilateral triangle faces, 6 edges and 4 vertices.
A triangular based based pyramid is a TETRAHEDRON. It becomes a regular tetrahedron if the four triangles, that make up its shape, are REGULAR, that is they are all the same size by area and shape; that is they are congruent. The word 'polyhedron' means a solid shape of any number of sides.
