Take the number of sides (N) and subtract from 2. Then multiply that by 180 degrees. The formula should look like this, (N-2) 180.
For example:
(N-2) 180
(4-2) 180
(2) 180
360 degrees

A polygon that all sides and angles are the same measurement is a regular polygon.
An n-sided polygon or n-gon, just like it sounds, has n sides. For example, a 13-sided polygon has 13 sides. A 24-gon has 24 sides.
The formula for determining the measurement of the interior angle of a general polygon with n sides is: 180°(n - 2)/n Given the 6-sided polygon, let n = 6. Then, by using the form above, we obtain: 180°(6 - 2)/6 = 30° * 4 = 120° Therefore, 120° is the measurement of the interior angle of a 6-sided regular polygon.
A "n-gon" has n sides.n-gon is a generic term to mean a polygon with 'n' sides where the 'n' is any whole number greater than 3.Examples:a 3-gon is a polygon with 3 sides, normally called a triangle;a 6-gon is a polygon with 6 sides, normally called a hexagon;a n-gon is a polygon with n sides.
The answer is N. An n-gon is shorthand for a polygon with n sides.
