Exploring Corresponding Angles
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:  
Answer the following questions:
1. As you move the slider, you observe that _________________________________________________________.
2. If a transversal intersects 2 ________________    ______________, then the corresponding angles are _____________________.  
3. If the pink angle above measures , its corresponding angle will be ____________. The grey angle will be ___________
4. Any other observations?
5. [Challenge Yourself] How can we show that the corresponding angle property is true?
