Angles in a quadrant are measured in the sexagesimal system, which divides a full circle into 360 degrees. In this system, each quadrant encompasses 90 degrees, allowing for straightforward expression of angular values in everyday contexts such as navigation, architecture, and engineering. The sexagesimal system is the most widely used system for angle measurement, making it particularly relevant for land surveying where precision and clarity are crucial.

In contrast to the sexagesimal system, radians are based on the radius of a circle, where a full circle is 2π radians. Grads, which represent another angular measurement system, divide a circle into 400 gradians, with each quadrant consisting of 100 gradians. Although both radians and gradians are valid systems, they are not typically used for describing angles in quadrants in most surveying practices. Angles of deflection pertain more to the direction of a line relative to a predetermined baseline, and do not refer specifically to the measurement system itself.
