Be sure to change the locations of the pentagon's BIG BLACK VERTICES each time before you drag the slider!!!
Note: The points on the pentagon's sides are midpoints.
Also note: For interior angles, you can make either the pink or green angle measure greater than 180 degrees (if you'd like)!
Questions:From your observations, what is the sum of the measures of the interior angles of
any pentagon?
