Find The Measure Of One Exterior Angle Of 12 Sided Polygon. A polygon is an enclosed figure that can have more than 3 sides. Exterior angle40 degrees for polygon of 9 sides.
A polygon is closed plane figure formed by the joining of three or more straight lines. Exterior angle of regular polygon is same Sincefrac3601524. Given one exterior angle learn how to find the number of sides of a polygon ex 2.
Hence the sum of the measures of the exterior angles of a polygon is equal to 360 degrees irrespective of the number of sides in the polygons.
Exterior angle of regular polygon is same Sincefrac3601524. For the triangle 180 - 60 120. Let us prove this theorem. Polygons and Angles Date Find the measure of one interior angle in each polygon.
