Answer 1

12. You also learned the formula for finding the area of any regular polygon if you know the length of one side and the apothem: A = (n × s × a)2 A = ( n × s × a ) 2 , where n is the number of sides, s is the length of one side, and a is the apothem.

10. Theorem 39: If a convex polygon has n sides, then its interior angle sum is given by the following equation: S = ( n −2) × 180°. The polygon in Figure 1 has seven sides, so using Theorem 39 gives: An exterior angle of a polygon is formed by extending only one of its sides.

11. The measure of each exterior angle of a regular hexagon is 60 degrees.
