Find The Measure Of One Exterior Angle Of 12 Sided Polygon. The sum of the measures of the angles of a convex polygon with n sides. Learn how to determine the measure of the interior angles of a regular polygon.
Ex 32 2 Find the measure of each exterior angle of a regular polygon of i 9 sidesWe know that Exterior angle 360𝑛 where n is the number of sides of regular polygon Given Number of sides of a regular polygon 9 Exterior angle 360 9 40 Ex 32 2 Find the measure of each exterior angle of a regular polygon of ii 15 sidesWe know that Exterior angle 360𝑛 where n is the number of sides of regular polygon Given Number of sides of a regular polygon 15 Exterior. The sum of the measures of the exterior angles of a convex polygon one angle at each vertex is 360 We can add the measures of all exterior angles of the above pentagon and the sum can be equated to 36 0. Let us prove this theorem.
120 degrees is the measure of the exterior angle.
And also we can use this calculator to find sum of interior angles measure of each interior angle and measure of each exterior angle of a regular polygon when its number of sides are given. The calculator given in this section can be used to know the name of a regular polygon for the given number of sides. Sum of all exterior angles360. Exterior angle of regular polygon is same Sincefrac3601524.
