SUM/Total of the interior angles of a polygon formula
S = (n-2)180
360 (I'm extending the lines of my polygon and eventually I'll go all the way around in a circle)
What do exterior angles of a polygon always add up to?
180 degrees (angles on a straight line).
What do x and y always add up to?
360/n
What is the formula for finding the exterior angle of a Regular Polygon?
(n-2) x 180
What is the formula for finding the sum of interior angles?
51.4 degrees (7 sides, regular means all the same so angles are also all the same, 360 total degrees for exterior angles so 360/7 = 1 exterior angle.)
What is the measure of one exterior angle of this regular heptagon (round to 1dp if needed)?
540. (n-2) x 180.
What is the sum of the interior angles of this polygon?
900. (n-2) x 180.
What is the sum of the interior angles of this polygon?
