Alternate Interior Angles Theorem

In the applet below, a TRANSVERSAL intersects 2 PARALLEL LINES. When this happens, there are 2 pairs of ALTERNATE INTERIOR 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 interior angles are _____________________. 2) If the pink angle above measures 134 degrees, what would the measure of its alternate interior angle be? 3) If we said that when parallel lines exist and you have a transversal that cuts through it, then we would say that the alternate interior angles are__________________________? 4) What is a converse to a statement or theorem? 5) What would the converse of statement 3 be?______________________________________________________________________________________________________________?
