Azimuth values typically vary over what range?

• A. Vary from 0 - 360.
• B. Vary from -180 to 180.
• C. Vary from 0 - 90.
• D. Vary from 0 - 180.

Answer: (B)

Azimuth is the angle a line makes with north, expressed in a signed way. Using -180 to 180 degrees lets you indicate direction with a sign: positive angles point east of north, negative angles point west of north, and zero means due north. This signed range makes it easy to compare directions and compute differences without having to wrap around at 360 degrees, which simplifies traverse calculations and directional updates. While some contexts use 0 to 360, the -180 to 180 convention is convenient for conveying both magnitude and direction in a single value.
