Azimuths are defined as what type of angles?

• A. Azimuths are horizontal angles observed clockwise from any reference meridian.
• B. Azimuths are horizontal angles observed counterclockwise from any reference meridian.
• C. Azimuths are the same as bearings.
• D. Azimuths are measured from magnetic north.

Answer: (A)

Azimuths are horizontal angles measured clockwise from a reference meridian. This means you choose a north-south line as your zero line (it could be true north, grid north, or magnetic north), and you measure the angle to the line toward the target by rotating clockwise. The result is a value between 0 and 360 degrees, which makes azimuths a consistent, unambiguous way to specify direction on the horizontal plane. This is why the description fits best: it emphasizes measuring clockwise from any reference meridian, rather than a specific north or a different convention. Bearings, while related, are typically given as quadrant descriptions (like N E or S W) rather than a single 0–360 value. And restricting the reference to magnetic north is too limiting, since azimuths can use any reference meridian.
