How To Find The Measure Of One Interior Angle In Each Polygon. Polygons and Angles Date Find the measure of one interior angle in each polygon. In order to find the measure of a single interior angle of a regular polygon a polygon with sides of equal length and angles of equal measure with n sides we calculate the sum interior angles or n 2 180 and then divide that sum by the number of sides or n.
I VCO 7 regular 24-gon 9 regular 23-gon I coo c 8 regular quadrilateral 10 16-gon Find the measure of one exterior angle in each polygon. You then subtract from the number of sides yielding. If a polygon has 5 sides it will have 5 interior angles.

To calculate the size of each angle in a regular 20-sided polygon you need to find the sum of the interior angles first. S n S n Here is an octagon eight sides eight interior angles. The sum of the measures of the interior angles of a convex n-gon is n - 2 180 The measure of each interior angle of a regular n-gon is 1n n - 2 180. Where S S the sum of the interior angles and n n the number of congruent sides of a regular polygon the formula is.
