Question

which shape could be thought of as being created by stacking congruent polygons?
cone
rectangular prism
square pyramid
triangular pyramid

Explanation:

Step1: Understand congruent polygons

Congruent polygons have same shape and size.

Step2: Analyze each option

A cone has a circular base and a curved surface, not made by stacking polygons. A square - pyramid and a triangular - pyramid have triangular faces and a base, and are not formed by stacking congruent polygons in the way described. A rectangular prism has two congruent rectangular bases and rectangular lateral faces. It can be thought of as stacking congruent rectangles (the bases are congruent rectangles).

Answer:

rectangular prism
