What will be the exterior angle of a polygon if the interior angle is 80 degrees?

Given :

The interior angle of a polygon is 80°.

To find :

We have to find he Exterior angle of polygon.

Solution :

We know that,

Sum of the interior angle and external angle in any polygon is equal to 180°.

Therefore,

The exterior angle of the polygon $= 180°-80° = 100°$.

The exterior angle of the polygon is 100°
