Do pyramids have perpendicular faces ?
4 for a triangular based pyramid and 5 for a square based pyramid
No, there are many different types of pyramids. To give a real-life comparison, the Egyptian pyramids are square pyramids, and have 5 faces. Triangular pyramids have 4 faces. (Count the base as one face) A pentagonal pyramid would have 6 faces. (Five on each side, plus the base) A hexagonal pyramid would have 7 faces, etc. (One for each side base + the base's face)
There would be 8 faces. Each square pyramid has 1 square face (its base) and 4 triangular faces. When you glue the squares together, you get a new polyhedron with 8 faces.
There are eight edges in a square based pyramid. There are also five faces and five vertices in square based pyramids.
To construct an octahedron using square pyramids, you need a total of 8 square pyramids. Each pyramid can be placed with its base facing outward, sharing a vertex at the center of the octahedron. This arrangement allows the pyramids to form the eight triangular faces of the octahedron.
Triangular pyramids have 4 faces(3 and a base) Traditional pyramids have 5 faces( 4 and a base)

There are lots of different types of pyramids but a square based pyramid has 5 faces, 5 corners and 8 edges
Four face.
