Alternate Exterior Angles
In the applet below, a TRANSVERSAL intersects 2 PARALLEL LINES.
When this happens, there are 2 pairs of ALTERNATE EXTERIOR ANGLES that are formed.
Guiding Questions:
1) Are alternate exterior angles congruent or supplementary?
2) If the pink angle above measures 146 degrees, what would the measure of its alternate interior angle be? What would the measure of the gray angle be?
3) As you moved the slider, what transformation(s) took place?
