Identify a pair of perpendicular 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. An angle between segment A B and segment A E measures 90 degrees.
