What kinds of face shapes are the results from cuts made from parallel and perpendicular to the bases of right rectangular prisms and pyramids

A cross section is the 2D shape that fallouts from cutting a 3D with a plane. To classify the face shape from cuts made parallel and perpendicular to the bases of right dimensional figures, we need to know first what parallel cuts are. These cuts will form the shape of the base while perpendicular cuts will take the form of the lateral face. Cuts at an angle through the right rectangular prism or pyramid will make a parallelogram.
