Angle Pairs

Line IJ is a transversal of the lines AB and CD.
In general, when we have a transversal cut two lines, we see angle pairs (corresponding angles, alternate interior angles, alternate exterior angles, same-side interior angles, and same-side exterior angles). Slide the lines to see these angle pairs keeping E between A & B, and keeping F between C & D. 1. List all the angle pairs 2. Define each type of angle pair and how to identify the angle pair based on their location.
