Do pyramids have perpendicular faces ?
ys
pentahedron examples: tetrahedron with one truncated corner, square pyramid
A truncated pyramid has: faces = number_of_edges_round_polygon_of_base + 2 vertices = number_of_edges_round_polygon_of_base x 2 edges = number_of_edges_round_polygon_of_base x 3
The description given seems to fit that of a square based pyramid.
In a triangular based pyramid, the three faces that form the base are perpendicular to the apex of the pyramid, which means they have pairs of perpendicular sides. The other three faces, which are triangular, do not have pairs of perpendicular sides.
5 faces do a square pyramid
A square pyramid has five faces.
A square pyramid has 5 faces. It has 1 square face and 4 triangle faces.
Number of faces on a square pyramid is 5.
There are five faces on a square based pyramid.
A rectangular pyramid, or a square pyramid, has 5 faces in all.
