Polygons:
▪ If all sides and all angles are equal, then the polygon is a regular polygon
▪ A regular polygon of n sides has n(n-3)/2 diagonals
▪ In a regular polygon of n sides, each exterior angle is 360/n degrees.
▪ Sum of measure of all the interior angles of a regular polygon is 180 (n-2) degrees (where n is the number of sides of the polygon)
▪ Each interior angle = 180(n−2)/n
▪ The sum of the measures of all the exterior angles of a regular polygon is 360 degrees.
