Understanding Angles and Degrees

This video tutorial explains the concept of a one degree angle and its use in measuring other angles. It covers the historical division of a circle into 360 degrees, the decomposition of a circle into fractional pieces, and the visualization of a one degree angle. The tutorial also discusses how angles are measured and recomposed using one degree units, providing a comprehensive understanding of angle measurement.

What is the primary purpose of understanding a one-degree angle?
