Question

all formulas in the chapter polygon​

Answer 1

Answer:

A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n - 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n - 2) * 180 / n

Answer 2

Answer:

(1) Area of polygon of perimeter p and radius r of in circle = 1/2×p×r

(2) sum of all the exterior angles =360

(3)Interior angle +corresponding angles =180

(4) the sum the interor angles of convex polygon having n sides is 180 (n-2)
