Identify a pair of parallel segments in the diagram. The figure shows two equal rectangles A B C D and E F G H in a space. The rectangles are located on parallel planes. Vertex A corresponds to vertex E. Vertex B corresponds to vertex F. Vertex C corresponds to vertex G. Vertex D corresponds to vertex H. The corresponding vertices are connected with segments. Segment C D is parallel to segment G H. Segment G C is parallel to segment H D. An angle between segment C G and segment F G measures 90 degrees.
