All angles in a regular polygon are equal. To find the total sum all all the interior angles, we have the formula
(n-2)180.
here, n=the number of sides in that polygon.
since the polygon is a regular polygon, all its interior angles will be equal.
for example,
if the interior angles of a regular polygon is given as 120, you should find the exterior angles at first.
if we are taking a linear pair, we'll get-180-120=60
here, 60 is the measure of each exterior angle. the exterior angles add upto 360. so if we divide 360 by 60, we'll find that there are 6 exterior angles.
which means 6 sides for that regular polygon.(regular hexagon.)
likewise, you can find the answer.
