Internal Angles Of Regular Polygons

To calculate the sum of the internal angles of a 6 sided polygon, use the formula ( n -2) x180 degrees where n represents the number of sides, so 4x 180 degrees = 720 degrees . Now to get one internal angle you need to divide 720 degrees by the number of sides, being 6 = 120 degrees. External angle can be found by dividing the number of sides into 360 , being 60 degrees. Using these methods you will be able to calculate any internal or external angle of a regular polygon
