No.
No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more.
45 degrees, which would be the interior angle of a equilateral triangle
Not possible - the smallest interior angle for a regular polygon is 60 degrees - which creates an equilateral triangle.
Yes. Pentadecagon (15-sided polygon)
it should be less than 180
The polygon with the largest interior angle is a regular polygon, specifically a regular polygon with the greatest number of sides. In a regular polygon, all interior angles are equal, and the formula for calculating the interior angle of a regular polygon is (n-2) * 180 / n, where n is the number of sides. As the number of sides increases, the interior angle also increases. Therefore, a regular polygon with a very large number of sides will have the largest interior angle.
160
An interior angle of 128 implies an exterior angle of 180-128 = 52 degrees. If so, the regular polygon has 360/52 sides ie 6.9 sides. A fractional side is not possible.
Smallest possible interior angle of regular polygon is 60 degrees (triangle). The greater the number of sides, the greater each interior angle. If exterior angle is 30 degrees, the polygon has 12 sides.
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
Each exterior angle of a regular polygon with n sides is 360/n degrees. Each interior angle of a regular polygon is 180 - Exterior angle. A direct formula for the interior angle is 180*(n-2)/n degrees.
