The sum of the exterior angles of all polygon is 360°. If ‘n’ is the number of sides.
Measure of an exterior angle = \(\frac{Sum\,of\,exterior\,angles}{No.of\,sides}\)
One outer angle = 360/n
(n = number of sides)
If the measure of an exterior angle is ‘x’.
x = \(\frac{1}{n}\times360 ^\circ\)
One outer angle and number of sides are inversely proportional. The constant of proportionality is 1/n.
