Find the angle of a regular polygon of 20 sides. Also find the external angle. Sum of the 20 equal angles = ( n -2 ) × 180o = 18 × 180o = 3240o Measure of one angle = 3240/20 = 162o Sum of the external angles = 360. Number of external angles = 20 measure of one external angle = 360o/55o = 18 How does the value 55 came?
