bearing

A bearing is a number between 0 and 360 that indicates direction.

Bearings:

* start from North (usually straight up the page)

* rotate in a clockwise direction from North

* have 3 digits 

Example 1

The angle between North and Point B is 77°.

We add a 0 to make the bearing have 3 digits.

Therefore, the bearing from A to B is 077°.

Example 2

The angle between North and Point B is 128°.

Therefore, the bearing from A to B is 128°.

Example 3

The angle between North and Point B is 318°. 

This is the reflex angle. The acute angle is only 42°. 

We must rotate in a clockwise direction from North and therefore must use 318°.

Therefore, the bearing from A to B is 318°.
