Q. 8 F

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

160°

Answer :

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.
