triangle... because pyramids are triangular therefore triangular pyramids have triangle faces
a cube * * * * * It cannot be a cube because a cube does not have 8 pairs of perpendicular faces - it has 12.
There is no such shape as a perpendicular prism.
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.
It has both.
Do pyramids have perpendicular faces ?
No, a dodecahedron doesn't have perpendicular faces
All of the adjacent faces are perpendicular. So there are 6 faces x 4 faces adjacent to each face So there are 24 perpendicular faces in a rectangular prism.
Triangular pyramids have 4 faces(3 and a base) Traditional pyramids have 5 faces( 4 and a base)
A pentagonal prism has only 7 faces. Each of the five lateral faces is perpendicular to the two bases: that makes 10 pairs of mutually perpendicular faces. In general, the lateral faces are not perpendicular, but four of them may be perpendicular to one or more of its neighbors - at most 4 more pairs. Still not 25!
Spheres, cones and cylinders have no perpendicular faces that meet each other at right angles.

Prisms with any number of sides can have perpendicular faces. Often both end faces are perpendicular to the length. In the case of a REGULAR octagonal prism, there will be four pairs of parallel faces, where each face of a pair will be perpendicular to the two faces of one of the other pairs. There is not much that can be said with certainty about an irregular octagonal prism.

A rectangular prism has six faces, and each of them is perpendicular to four others.
