There are 257 topologically different convex octahedra. Many of these will have no parallel faces. It can have four pairs of parallel faces.
A pyramid never has parallel faces. Any two faces intersect.
Pentagonal pyramids have six faces, ten edges, and six vertices. One of the faces is a pentagonal base, the rest are triangular.
Zero parallel faces in a triangular pyramid. There are four faces, and none of them are parallel to each other.
Do pyramids have perpendicular faces ?
Yes. A square consists of two pairs of parallel lines!
No, pyramids of any kind will never have any parallel faces. This is because all of the faces, excluding the base, must meet at a single point.
Triangular pyramids have 4 faces(3 and a base) Traditional pyramids have 5 faces( 4 and a base)
No.
A cube has three pairs of parallel faces and all faces are congruent.
triangle... because pyramids are triangular therefore triangular pyramids have triangle faces
A dodecahedron has 0 parallel faces
its has parallel faces and edges
