What is the unit of angular measure called gon based on?

The unit of angular measure called gon, also known as gradian or centigon, is based on the idea that a full circle or revolution is divided into 400 equal parts. Each part is one gon, meaning that one complete revolution equals 400 gon. This system provides a different perspective on angular measurement compared to degrees or radians.

The use of gons can be particularly advantageous in specific fields like surveying, as it allows for easier calculations in rectangular coordinates. For example, a right angle is 100 gons, which can simplify mental calculations when working with angles commonly encountered in surveying.

Understanding that there are 400 gons in a full revolution is key in scenarios where this unit of measure is applied. It highlights an alternative system that can be used effectively alongside degrees and radians, each of which serves its own purpose and applications in various fields of mathematics and science.
