. Write the Definition of Complete Angle
If after one complete rotation, the final ray coincides with the incident or initial ray, then the angle so formed is referred to as the complete angle. The different names are a complete angle and a round angle. The angle is same to 2π radians = 360 degrees similar to the central angle of a whole circle. Four right angles or straight angles make a complete angle. The angle is just like a zero angle however the difference is the amount of rotation.
