Angle Pairs

Line EF 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. 1. List all the angle pairs 2. Define each type of angle pair and how to identify the angle pair based on their location.
