Same Side Exterior Angles
In the applet below, a TRANSVERSAL intersects 2 PARALLEL LINES.
When this happens, there are 2 pairs of SAME-SIDE EXTERIOR ANGLES that are formed.
Guiding Questions:
1) Are same side exterior angles congruent or supplementary?
2) If the gray angle above measures 110 degrees, what would the measure of its same-side exterior angle be?
3) As you dragged the slider, what transformation(s) took place?
