Answer» We know that polyhedron is a solid, which is bounded by four or more polygonal faces in such a way that pairs of faces meet along edges and three or more edges meet in each vertex, therefore, (i) It is not possible that a polyhedron has 3 triangles for its faces. (ii) 4 triangles can be the faces of a polyhedron. (iii) A square and 4 triangles can be the faces of a polyhedron. |
