Which instruments can be used to measure an azimuth?

The ability to measure an azimuth accurately is essential in navigation and map reading. A compass is specifically designed to determine directions relative to the Earth's magnetic field, allowing users to find bearings expressed in degrees from true north. This makes it an ideal tool for measuring azimuths, which indicate the angle between a reference direction (usually true north) and a point of interest.

A protractor complements the compass by facilitating the ability to measure and plot angles directly on a map. By aligning the protractor along a line of sight on the map, you can accurately establish the azimuth you wish to navigate toward. Together, the compass for determination and the protractor for measurement provide the necessary tools to effectively work with azimuths in land navigation.

Other options, such as a ruler and tape measure, are primarily used for measuring distance rather than angles or bearings, making them unsuitable for measuring azimuths. Similarly, a GPS can provide directional information and coordinates but does not directly measure azimuths in the same way a compass does. Measuring wheels and components like maps and scales are also focused on distance and representation rather than angle measurement. Thus, the combination of a compass and a protractor is the most appropriate choice for effectively measuring an azimuth.
