Q8 F of 59 Page 195

Let’s find whether the following measurement of each interior angle is possible for a regular polygon-

160°


We know the basic formula for the sum of all interior angles of a polygon with n sides.


Here measure of each interior angle = 160°










n = 360 / 20


n = 18


Since the number of sides is a whole number, the given interior angle is possible for regular polygon.


The regular polygon has the total number of sides which is equal to 18.
