What is the term for a horizontal angle measured clockwise from north?

The term for a horizontal angle measured clockwise from north is known as an azimuth. In surveying and navigation, the azimuth is measured in degrees from 0° to 360°, with 0° indicating true north, 90° indicating east, 180° indicating south, and 270° indicating west. This method of measuring angles provides a clear and concise way to communicate direction, essential in land surveying and other applications where precise location and orientation are critical.

Bearing, while related, typically refers to the angle measured from a reference direction to a specific point but may not always designate a clockwise measurement from north. Angle of declination refers to the angle between magnetic north and true north, which is not directly relevant to the measurement of horizontal angles in a clockwise manner. Inclination generally refers to the angle of an object with respect to the horizontal plane, which does not apply here either. Thus, azimuth is the appropriate term for angles measured in the manner described in the question.
