What fraction of the total angle is the unfolded angle? What percentage of the full angle is the turned angle?

According to the theory of geometry and angles on a plane, a full angle is 360 degrees or π, and an expanded angle is 180 or π / 2.
To find out what part is the unfolded angle of the full one, we divide the degree measure of one by the second.
180/360.
Reduce the fraction by 10: 18/36.
Reduce the fraction by 9: 2/4.
And let’s cut it by 2: 1/2.
Answer: The unfolded angle is 1/2 of the full angle.
