## Interior Angles of Polygons

In order to find the value of the interior angle of a regular polygon, the equation is ((n-2)180^@)/n where n is the number of sides of the regular polygon. Triangle: ((3-2)180^@)/3 = 60^@ Square ((4-2)180^@)/4 = 90^@ Pentagon ((5-2)180^@)/5 = 108^@

## How to Find the Interior Angles of a Polygon

In the sum of interior angles, (n 2) 180 degrees equals (102) 180 degrees equals 8 180 degrees equals 1440 degrees. And for a Regular Decagon, the following is true: Each inner Free time to spend with your family and friends
