to find the sum of an interior angle...
FOR EXAMPLE: if you had a triangle, the total amount of degrees would be 180 degrees. now you must divide that from the number of sides...
180 divided by 3 = 60 so 1 interior angle would be 60 degrees
therefore, one EXTERIOR angle would be 120 degrees because 60 + 120 = 180 degrees or a straight line
hope this helps
did u know I'm only 11? god I'm pretty smart! ;)

How do you find the sum of the measures of the angles in polyons with out using a protractor?
(number of sides - 2)*180 = sum of interior angles
How do you find the sum of angles in a n-sided polygon to give an expression for the measure of each interior angle of a regular n-gon?
It is: (number of sides -2)*180 = sum of interior angles If its a regular polygon then: sum of interior angles/number of sides = each interior angle
