In Section 8.2, we covered triangles and polygons. We learned that the sum of the angles inside a triangle is 180 .

We also had a formula for determining the sum of the angles inside any polygon based on how many triangles you could "find" inside the figure.

This interactive animationLinks to an external site. allows us to really "see" how the sum of the interior angles of any polygon is determined.

Play with the polygons in the animation by changing their size, moving the vertices, lengthening the sides, and so on. Then use the slider to see the magic!

Comment on your favorite polygon animation and explain how what is done in the animation relates to the formula given in the class notes.
