Pentagon: Interior Angles

[color=#000000]Interact with the app below for a few minutes.  Then answer the questions that follow.  [br][br]Be sure to change the locations of the pentagon's [b]VERTICES[/b] each time [i]before[/i] you drag the slider. [br][br]Note: The points on the pentagon's sides are [i]midpoints. [/i][/color]
What geometric transformations took place in the app above?
[color=#000000]Did any of these transformations change the measures of these interior [/color][color=#000000]angles?  If so, explain how. If not, explain why not. [/color]
From your observations, what is the sum of the measures of the interior angles of [i]any pentagon?  [/i]
