Revolution
The revolution is the simplest method of measuring the angle. We define one revolution as the complete rotation of the circle. We define revolution such that,
One Revolution = 2π Rad = 360°
Thus, we can say that half revolution is π Rad or 180° and so on.
The below table shows the relationship between degree, radian, and revolution:

Measuring Angles
Measurement of angles is very important in geometry for solving various geometrical problems and comparing angles in various geometrical figures. We use various geometric tools such as a protractor, and a compass for measuring angles. There are various types of angles measured by us and before learning more about measuring angles we should first learn more about what is an angle.
Let’s learn more about Angles, measuring angles, degrees, radians, and others in detail in this article.
