Questions and Answers

Which formula can be used to find the sum of the interior angles of a regular polygon?

Sum of Interior Angles = (n - 2) * 180

Sum of Interior Angles = (n + 2) * 180 / n

Sum of Interior Angles = n * 180

Sum of Interior Angles = (n - 2) * 180 / n (correct)

Which formula can be used to find the measure of just one interior angle of a regular polygon?

Measure of Interior Angle = (n - 2) * 180 / n (correct)

Measure of Interior Angle = n * 180

Measure of Interior Angle = (n - 2) * 180

Measure of Interior Angle = (n + 2) * 180 / n
