A full circle measures 360°. When two rays form an angle by making an half-turn of 360°, the measure of the angle is 180 degrees.

The image attached below shows the half-turn of the rays of the angle formed.

Therefore, the rays that makes an half-turn of 360 degrees forms an angle that measures 180 degrees (see attachment).
