All faces of a pyramid are always:
(a) Triangular
(b) Rectangular
(c) Congruent
(d) None of these

Solution:

We know that

A pyramid is a 3D polyhedron with the base of a polygon along with three or more triangle-shaped faces that meet at a point above the base.

The triangular sides are called faces and the point above the base is called the apex.

A pyramid is made by connecting the base to the apex.

Sometimes, the triangular sides are also called lateral faces to distinguish them from the base. In a pyramid, each edge of the base is connected to the apex that forms the triangular face.

Therefore, all faces of a pyramid can be triangular and rectangular.
