Question

what figure results from a vertical cross section of a rectangular pyramid? rectangle triangle circle trapezoid

Explanation:

A rectangular pyramid has a rectangular base and triangular faces. A vertical cross - section (a cross - section that passes through the apex and is perpendicular to the base) will intersect two adjacent triangular faces and the base. The intersection of the cross - section with the two triangular faces and the base forms a triangle. A rectangle would require parallel sides in a different orientation than what a vertical cross - section of a pyramid provides. A circle is not possible as the pyramid has straight edges. A trapezoid has one pair of parallel sides, but a vertical cross - section of a rectangular pyramid does not create that shape.

Answer:

Triangle
