Describe the two dimensional figure that results from making a perpendicular slice to right rectangular pyramid that goes from the base to the Apex

Answer 1

The two-dimensional figure resulting from making a perpendicular slice to a right rectangular pyramid from the base to the apex would be a triangle. The base of the triangle would be one of the rectangular faces of the pyramid, and the apex would be the point where the perpendicular slice intersects the opposite face. The sides of the triangle would be the edges of the pyramid that connect the base to the apex. This triangle would be a right triangle since one of its angles would be a right angle.
