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 โ 2) 180ยฐ = n ร interior angle Interior angle = ((๐ โ 2))/๐ ร 180ยฐ Interior angle = (1โ2/๐) ร 180ยฐ For the interior angle to be minimum, (1โ2/๐) 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
