Question

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

Explanation:

Step1: Analyze each option

• Cone: A cone has a circular base (a non - polygon) and a curved surface. It cannot be formed by stacking congruent polygons.
• Rectangular prism: A rectangular prism has two congruent rectangular bases and four rectangular lateral faces. If we consider the cross - sections parallel to the bases, they are all congruent rectangles (polygons). We can think of a rectangular prism as being created by stacking congruent rectangles (polygons) along a perpendicular direction.
• Square pyramid: A square pyramid has a square base and triangular lateral faces. The cross - sections parallel to the base are squares of decreasing size (not congruent).
• Triangular pyramid: A triangular pyramid has a triangular base and triangular lateral faces. The cross - sections parallel to the base are triangles of decreasing size (not congruent).

Answer:

rectangular prism
