Each interior angle is 162 degrees.
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.
160
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.
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.
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
If each interior angle is 178 degrees then the regular polygon will have 180 sides.
A regular polygon with each interior angle measuring 120 degrees is a hexagon.
The interior angle of a regular polygon with x sides is 180(x-2)/x. As a result, each angle of a regular 50-sided polygon is 172.8.
There is no regular polygon with an interior angle of 20o. If the interior angle is 120o then there are six sides and the sum of the angles is 720o.
The only regular polygon with an interior angle of 90 degrees is the square, which has four sides. Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons.
If the measure of an interior angle of a regular polygon is 140o, the polygon is a nonagon (sometimes called an ennagon) having 9 sides.
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
