Draw Angles - Plotting Program. A circle has a total of 360 degrees all the way around the center, so if that central angle determining a sector has an angle measure of 60 degrees, then the sector takes up 60/360 or 1/6, of the degrees all the way around. The angle which measures greater than 180° and less than 360° is known as the reflex angle. And the two straight sides are called arms. Is Betty White close to her stepchildren? Downloads.
