Exploring Corresponding Angles (V2)

In the applet below, a TRANSVERSAL intersects 2 PARALLEL LINES. When this happens, there are 4 pairs of corresponding 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: If a transversal intersects 2 ________________ ______________, then corresponding angles are _____________________. 2) If the pink angle above measures 52 degrees, what would the measure of its corresponding angle be?  What would the measure of the gray angle be? 3) As you moved the slider, what transformation took place?
