What unit of measurement is used for an intersection angle?

The unit of measurement used for an intersection angle is degrees, which are commonly used in construction, surveying, and many other fields of engineering. Degrees provide a straightforward way to express angles, with a full circle representing 360 degrees. This familiarity makes it particularly practical for applications like road design and layout planning, where precise angle measurements are essential.

Radians are another measurement unit used in mathematics and physics, often more suitable for theoretical contexts, particularly in relation to circles where relationships to the radius are considered. Gradians are another angle measurement unit that is less commonly used, consisting of 400 units for a full circle, making them more common in specific applications such as surveying in some regions. Meters, on the other hand, are a unit of length and are not applicable for measuring angles. Thus, the choice of degrees aligns with standard practice and acceptance in fields that handle intersection angles.
