Question

any polyhedron can be the base of a pyramid.
a. true
b. false

Explanation:

A pyramid is defined as a polyhedron with one face (the base) being a polygon and the other faces being triangles that meet at a common vertex. A polyhedron is a three - dimensional solid with flat polygonal faces, straight edges and vertices. Since the base of a pyramid is a polygon and a polyhedron has polygonal faces, any polyhedron can potentially serve as the base of a pyramid.

Answer:

A. True
