In mathematics, a bearing is defined as an angle measured clockwise from north. Bearings are usually written as a three-figure bearing, for example, the angle 50° from north is written as 050°. Bearings are used in navigation to describe the direction of travel. To measure a bearing, we must first know which direction is north. Bearings are important for navigation in 2-dimensions such as when using maps. The true bearing is the angle measured clockwise from north. The relative bearing is the angle between the direction of travel and some other direction.

To calculate a bearing, we need to find the angle clockwise from north. We can start by drawing a vertical line representing north at the first location. Then, we can draw a line connecting the start location to the end location and measure the clockwise angle between the north line and this line. For example, the bearing from A to B is 100°, which is the angle from north clockwise to B. The bearing from B to A is 280°, which is the angle from north clockwise to A.

Bearings are used in various fields such as navigation, surveying, and engineering. They are also used in mathematics to solve problems related to distance and direction.
