[color=#000000]Interact with the applet below for a few minutes.  [br]Then, answer the questions that follow.  [br][br]Be sure to change the locations of the heptagon's [b]BIG BLACK VERTICES[/b] each time [i]before[/i] you drag the slider!!! [br][br]Note: [i]Each point on a side of this he[/i][i]ptagon is a midpoint. [/i][/color]

[b][color=#980000]Questions:[/color][/b][br][br][color=#000000]1) What geometric transformations took place in the applet above?[br]  [br]2) When working with the heptagon's interior angles, did any of these transformations [br] change the measures of these interior angles?  [br][br]3) From your observations, what is the sum of the measures of the interior angles of[br]    [i]any heptagon?  [br][/i][br]4) When working with the heptagon's exterior angles, did any of these transformations change the measures of these exterior angles? [i][br][br][/i]5) From your observations, what is the sum of the measures of the exterior angles of[br]    [i]any heptagon?  [/i][/color]
