1 answer

B. triangle

When a perpendicular slice is made from the base through the apex of a right rectangular pyramid, the resulting two-dimensional figure is a triangle. The base of the pyramid is a rectangle, and the slice cuts through the rectangular base and the apex of the pyramid, creating a triangle shape.
