Angles Of a POLYGON Can you win the MILLION Dollars?

Do you know that the sum of the exterior angles of a polygon is always 360 degrees?

Do you know that if you multiply 180 degrees by 2 less than the number of sides that you will have found the sum of the interior angles of the polygon?

If you know either one of the sums then you can divide that by the number of sides and you will then know the size of one angle (if it is regular polygon).

One last item to know. I find it very helpful when I get stuck. One interior angle added to one exterior angle of a regular polygon always = 180 degrees.
