The sum of all interior angles in a polygon with sides (, ) is equal to . (Credit: Mathsisfun.)
The polygon here has 6 sides. . Its interior angles shall add up to .
Consider the properties of a regular polygon. (Credit: Mathsisfun.)All sides in a regular polygon are equal in length. All angles in a regular polygon are also equal.
There are six interior angles in a polygon with 6 sides. All six of them are equal. Thus, each of the six interior angle will be
