Interior Angles between Parallel Lines
Line AE is parallel to line FD. Line CB is the transversal. Use this applet to explore the relationships between interior angles. Move point A change the orientation of the parallel lines. Move point C to change the distance between the lines. Point B changes both orientation and distance between the lines.
