A pyramid is a polyhedron whose lateral faces are
(a) Rectangles
(b) Triangles
(c) Parallelograms
(d) Rhombuses or Rhombi

Solution:

We have to find the shape of the lateral faces of a pyramid.

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, the lateral faces of a pyramid are triangles.

✦ Try This: In a pyramid, the number of faces and the number of vertices are (a) equal, (b) different, (c) half of the other, (d) none of the above
