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 is a triangle. The triangle is formed by the intersection of the slice with the base of the pyramid, and the three sides of the triangle are formed by the edges of the pyramid that meet at the apex.
