Planes ABC and EFG are parallel because those are the planes given as parallel. Planes BCG and ADH are parallel, as well as planes ABF and DCG because opposite sides of a rectangular prism are parallel the same way opposite sides of a rectangle are parallel. 2. Plane ABF intersects plane ABC at AB ; plane DCG intersects plane ABC at DC ; plane ADH intersects plane ABC at AD ; plane BCG intersects plane ABC at BC.
