How is the sexagesimal system structured?

The sexagesimal system is structured by dividing a circle into 360 degrees. This system originated from the ancient Sumerians who used a base-60 numbering system, which has influenced various aspects of mathematics and astronomy throughout history. The choice to use 360 degrees in a circle is practical because it allows for the easy division of the circle into equal parts, leading to many subdivisions that are mathematically convenient—such as 30, 45, and 60 degrees. Additionally, the number 360 is highly composite, meaning it has many divisors, which facilitates calculations and the measurement of angles. This degree-based system is widely adopted in geometry, navigation, and other fields, solidifying its significance in both historical and modern contexts.
