Question

He Polygon Angle-Sum Theorem states the following: The sum of the measures of the angles of an n-gon is ____.

Answer 1

According to the angle-sum theorem, the  sum of the measures of the angles of an n-gon is expressed in the formula B. (n – 2)*180. This is verified in a simplt triangle, in which the total sum of the angles inside is 180 with n of the polygon equal to 3. Hence, (3-2)*180 equal to 180 degrees.
