# G.GCO.8 Exploring 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. Interact with the applet below for a few minutes, then answer the questions that immediately follow.**Directions & Questions:**1) Complete the following statement: I

**f a transversal intersects 2 ________________ ______________, then same-side exterior angles are _____________________.**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?
