Interact with the applet below for a few minutes, then answer the questions that follow.
Feel free to move the

**BIG PINK POINTS**anywhere you'd like before sliding the slider.**Questions:**1) What geometric transformations took place in the applet

*after*the triangle was made? List them. 2) Did any of these transformations change any segment lengths or angle measures? 3) How would you classify this triangle

*by its sides?*4) Given what you've observed, how would you classify this triangle

*by its angles?*5) What is the measure of each pink angle? Clearly explain how you know this must be true. 6) How many degrees did a pink angle rotate after it was translated to another vertex? 7) Use your responses for (3), (4), and (5) to fill in the blanks to make a true statement:

**If a triangle is ____________________, then it is also _______________________. Each angle of a/an ________________________ triangle measures _____________.**
