How To Find The Measure Of One Interior Angle In A Polygon. Then to find one individual angle we divide by the total number of angles. N 2 x 180.
Choose one vertex or corner of the polygon and draw straight lines joining this vertex to all. Then to find one individual angle we divide by the total number of angles. Polygon Exterior Angles Theorem.
The sum of the measures of the exterior angles of a convex polygon one angle at each vertex is.
2 X Research source. Its just that the angles arent all congruent so you cant divide by n to get the individual measures. To find the measure of one angle the formula is 360n where n is the number of the sides of the 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.
