What is the degrees for a regular polygon?
If you name the degree of the angle d, then the exterior angle is 180 - d. The exterior angles have to add up to 360, a full circle to get back to where you started. So if there are nsides and n angles,n(180-d) = 360Solving for d, you get180 n - nd = 360-nd = 360 - 180n-d = 360/n - 180and thend = 180 - 360/n

What is the name of an angle from 181 degrees to 359 degrees?
An angle from 181 degrees to 359 degrees is called a reflex angle. A reflex angle is an angle that measures greater than 180 degrees but less than 360 degrees. It is formed by rotating a ray less than one full revolution, resulting in an angle that extends beyond a straight line.
