Formula For Exterior Angles Of A Polygon

S 360 also the measure of each exterior angle of an equiangular polygon 360 n.

The formula for calculating the size of an exterior angle is. The exterior angle of the regular pentagon is given as the frac 360 0 5 72 0. If you know the exterior angle you can find the interior angle using the formula. Therefore s 180n 180 n 2 s 180n 180n 360.

Since you are extending a side of the polygon that exterior angle must necessarily be supplementary to the polygon s interior angle. 360 div number of sides. By using this formula easily we can find the exterior angle of regular polygon. The sum of exterior angles of a polygon is 360.

Exterior angle of a polygon 360 number of sides. The exterior angle of a regular n sided polygon is 360 n worksheet using the formula for the sum of exterior angles. For any closed structure formed by sides and vertex the sum of the exterior angles is always equal to the sum of linear pairs and sum of interior angles. Now let us take some polygons and we will try to find out the each exterior angle of it.
