Alternate Exterior Angles Theorem
In the applet below, a TRANSVERSAL intersects 2 PARALLEL LINES.
When this happens, there are 2 pairs of ALTERNATE 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: If a transversal intersects 2 ________________ ______________, then alternate exterior angles are _____________________.
2) If the pink angle above measures 146 degrees, what would the measure of its alternate exterior angle be? What would the measure of the gray angle be?
3) As you moved the slider, what transformation(s) took place?
4) If we said that when parallel lines exist and you have a transversal that cuts through it, then we would say that the alternate exterior angles are__________________________?
5) What is a converse to a statement or theorem?
6) What would the converse of statement 4 be?
