Describe the two-dimensional figure that results from making a perpendicular slice to a right rectangular pyramid that goes from the base through the apex.(1 point)

The two-dimensional figure that results from making a perpendicular slice to a right rectangular pyramid that goes from the base through the apex would be a triangle. This triangle would have one right angle where the slice intersects the base of the pyramid, and the other two angles would be acute angles formed by the sides of the pyramid meeting at the apex.
