What is the relationship between true bearing and compass bearing?

True bearing and compass bearing represent two different systems of measuring direction, and understanding their relationship is essential in navigation.

True bearing is defined as the angle measured clockwise from true North (0°) around to the object in question. It ranges from 0° to 360°, providing a consistent method for indicating direction.

On the other hand, compass bearing uses a different approach. It divides the compass into four quadrants: North, East, South, and West. Each direction is then indicated by a combination of these cardinal points, expressed in degrees from North, but can be measured in either a clockwise or counterclockwise direction. For example, an object located directly East would have a compass bearing of 90°, while an object to the West could be indicated as either 270° (clockwise) or by using West as a cardinal point (W).

Given this understanding, the correct choice is that true bearing is measured clockwise from North, while compass bearing can be either clockwise or counterclockwise, depending on the direction specified. This distinction highlights the unique characteristics of both measurement systems and emphasizes the correct interpretation of the directional data in navigation contexts.
