Find The Measure Of One Exterior Angle Of A Regular 12-sided Polygon. The sum of measures of angles of a convex quadrilateral 360 Yes this property holds even if the quadrilateral is not convex. Exterior angle40 degrees for polygon of 9 sides ii.
The measure of each exterior angle 360n where n number of sides of a polygon. N - 2 180 n. Now You divide 360 by the measure.
The sum of the measures of the angles of a convex polygon.
Each exterior angle is 30. So divide 360 by the dodecagons twelve exterior angles. No matter the shape a regular polygon can have its exterior angles add to no more than 360. The measure of each interior angle of a regular n-gon is.
