Question by Kay: what are the formulas for finding interior and exterior angles of polygons?
this is for geometry and i haven’t been in class due to illness… and i have no idea… any help would be great… thanks!

Answer by Adam_Nelson
Interior angles of a regular polygon is 360 divided by the number of angles in the polygon. Exterior angles each/all 180-interior angles. If it’s regular it’s 180-360/n.
Good luck!

for side n, sum of interior angles = (n-2)180
and sum of exterior = 360 for all n sides

The sum of the exterior angles of any polygon add up to 360 degrees, so if the polygon is regular and has n-sides, the exterior angle is 360/n
The angle sum of the interior angle of a polygon of n sides is (2n – 4) right angles.
