What defines an azimuth?

1. An angle less than 90° within a quadrant

2. An angle measured counterclockwise

3. An angle between 0° and 360° measured clockwise from North

4. An angle measured from the vertical line

The correct answer is: An angle between 0° and 360° measured clockwise from North

An azimuth is defined as an angle measured from a reference direction, typically true North, and is quantified within the range of 0° to 360°. In practical terms, an azimuth indicates the direction to a specific point in the horizontal plane by measuring the angle clockwise from North. This system allows surveyors and map users to represent directions clearly and uniformly, enabling effective communication and navigation. The other options describe different concepts. An angle less than 90° within a quadrant might refer to a specific category of angles but does not encompass the full definition of azimuth. Measuring an angle counterclockwise can be related to other systems of angular measurement, yet azimuth specifically refers to a clockwise measurement from North. Lastly, measuring an angle from the vertical line pertains more to vertical angles rather than the horizontal measurements that azimuth entails. Thus, the definition of azimuth focuses purely on the horizontal angular measurement starting from North, making it a crucial concept in land surveying and navigation.
