    This is why we have to learn proofs:
    They are useful. They will let you answer anyone who asks you, "Well...why?" They will give you a great sense of satisfaction. They are cool.Geometry PASS Standard 2.3b requires them.

    Go watch the video on the "Exterior Angle Sums" page. Know how they derive the formula for the sum of the interior and exterior angles by showing how many triangles are in a polygon.

    You can also find the exterior angle measures of a regular polygon by using either the value you obtained for the interior angles, or by a simpler method... This lady will elaborate on both. Please excuse her accent, everything else about her explanation is superb.

    Now it's your turn!!
    Take a picture of a polygon in the real world. Just posting a picture will earn you one point. For an additional one point each, you will have to tell me the shape's name, whether it is concave or convex, whether it is regular or irregular, what the sum of its interior angle measures are (or what a single interior angle is if it is a regular polygon), and what the sum of its exterior angles are (or what an individual one is if it is a regular polygon), and why you chose it.
    This makes for a total of 7 points. A 6/7 is an 85%, which is my goal for all you, so show me what you've got!
