Question

a rectangular pyramid is sliced so the cross section is parallel to its base. what is the shape of the cross section? pentagon trapezoid rectangle triangle

Explanation:

When a rectangular pyramid is sliced parallel to its base, the cross - section has the same shape as the base. Since the base of a rectangular pyramid is a rectangle, the cross - section will also be a rectangle. A pentagon has five sides, a trapezoid has four sides with one pair of parallel sides (not the same as a rectangle), and a triangle has three sides.

Answer:

rectangle
