Ex 3.2, 6 (a) What is the minimum interior angle possible for a regular polygon? Why?We know that Sum of angles of a regular polygon = Number of sides ร— interior angle (n โˆ’ 2) 180ยฐ = n ร— interior angle Interior angle = ((๐‘› โˆ’ 2))/๐‘› ร— 180ยฐ Interior angle = (1โˆ’2/๐‘›) ร— 180ยฐ For the interior angle to be minimum, (1โˆ’2/๐‘›) should be minimum. The value of the interior angle will keep on increasing as the number of sides increases Thus the minimum interior angle possible for a regular polygon is 60ยฐ
