Question

All faces of a pyramid are always:

• A. Triangular
• B. Rectangular
• C. Congruent
• D. None of these

Answer 1

The correct option is D

None of these

Explanation for the correct option:

Option (D) None of these

The faces of pyramids can be rectangular and triangular.

A pyramid is a three-dimensional shape. A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex. A pyramid is formed by connecting the bases to an apex. Each edge of the base is connected to the apex and forms the triangular face, called the lateral face. If a pyramid has an n-sided base, then it has $n+1$ faces, $n+1$ vertices, and $2n$ edges. Based on the shape of the base of the pyramid, the pyramid is classified as a triangular pyramid, square pyramid, pentagonal pyramid.

Hence, option (D) is the correct option.
