the angle sum of a pentagon is 540.
You do not need to find. If it is a parallelogram, it must be 180 degrees.
An angle sum is the sum (in degrees) of the particular angles you are measuring.
With a protractor and the sum of the interior angles are 360 degrees.
It means the sum of the angle measurements.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. Once you have the sum, divide by the number of sides to find an individual angle.
The sum of the exterior angles of a 2D planar polygon is always 360 degrees.
If it is a scalene triangle then: 180 - the sum of the 2 known angles = x angle
