View the full answer.Sum of Interior Angles of a Polygon. The Sum of interior angles of a polygon is always a constant value. If the polygon is regular or irregular, the sum of its interior angles remains the same. Therefore, the sum of the interior angles of the polygon is given by the formula: Sum of the Interior Angles of a Polygon = 180 (n-2) degreesQ.2. By using the sum of exterior angles formula, prove that each interior angle and its corresponding exterior angle in any polygon are supplementary. Ans: To prove: The sum of an interior angle and its corresponding exterior angle is \({180^{\rm{o}}}.\) Let us consider a \(n-\)sided polygon. By using the sum of exterior angles formula,Consider the sum of the measures of the exterior angles for an n -gon. The sum of the measures of the exterior angles is the difference between the sum of measures of the linear pairs and the sum of measures of the interior angles. That is, the sum of the exterior angles n is. N = 180n − 180(n − 2) Distribute 180 . N = 180n − 180n + 360 ...The interior angle of a regular 21-gon is around 162.86^@. The sum of interior angles in a polygon with n corners is 180(n-2) A 21-gon therefore has an interior angle sum of: 180(21-2)=180*19=3420^@ In a regular 21-gon, all interior angles are equal, so we can find out the measure of one of these angles by dividing 3420 by 21: 3420/21~~162.86To find the sum of the interior angles of a dodecagon, divide it up into triangles...
