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 _____________.
