[color=#000000]Interact with the applet below for a few minutes. [br]Then, answer the questions that follow. [br][br][/color][i][color=#980000]Be sure to change the locations of the triangle's WHITE VERTICES each time before you drag the slider!!! [/color][/i]
1) What geometric transformations took place in the applet above?
[color=#000000]2) When working with the triangle's interior angles, did any of these transformations [br] change the measures of the [/color][color=#0000ff]blue[/color] [color=#000000]or[/color] [color=#6aa84f]green[/color] [color=#000000]angles?[/color]
3) From your observations, what is the sum of the measures of the interior angles of [i]any triangle? [/i]
[color=#000000]4) When working with the triangle's exterior angles, did any of these transformations change the measures of the [/color][color=#6aa84f]green[/color][color=#000000] or [/color][color=#999999]gray[/color][color=#000000] angles?[/color]
