Question

any polyhedron can be the base of a pyramid.

a. true
b. false

Explanation:

Analyze the definition of a pyramid

A pyramid is a three-dimensional solid (a polyhedron) where the base is a polygon, and the lateral faces are triangles that meet at a single point (the apex).

Analyze the definition of a polyhedron

A polyhedron is a three-dimensional solid bounded by flat polygonal faces. It is a 3D object, not a 2D flat shape.

Evaluate the statement

The base of a pyramid must be a two-dimensional polygon (such as a triangle, quadrilateral, or hexagon), not a three-dimensional polyhedron. Therefore, a polyhedron cannot be the base of a pyramid.

Answer:

• A. True
• B. False (Correct answer)
