Remember: Each exterior angle of a regular polygon of n sides=
360°
n
Now,
360°
70°
≠ an integer So, there exists no regular polygon whose exterior angle is 70°. Hence, statement 1 is incorrect. For n ≥ 5, Each exterior angle of a regular polygon ≤
360°
5
=72° Thus, the exterior angle of any regular polygon of n (n ≥ 5) sides is acute. Hence, statement 2 is correct.
