An azimuth is the angle measured in which direction from a north base line?

An azimuth is the angle measured in which direction from a north base line?

• A. Clockwise direction
• B. Counterclockwise direction
• C. From east toward west
• D. From south toward north

Answer: (A)

Azimuth is defined as the angle measured clockwise from a north reference. Start at north and rotate to the right; that clockwise sweep determines the azimuth. For example, pointing east corresponds to an azimuth of 90 degrees, south to 180 degrees, and west to 270 degrees. This convention aligns with how a compass rose is laid out, with angles increasing as you move clockwise from north. Measuring counterclockwise from north would yield a different system (often referred to in other contexts as back-azimuth or a different bearing convention), and starting from east or from south would not use the north-based baseline that defines azimuth.
