This document discusses bearings and how to solve problems involving bearings. It contains the following key points: - Bearings are measured in degrees in a clockwise direction from North and written as 3 figures. - Examples are provided for measuring and calculating bearings between different points on diagrams. Problems involve finding unknown bearings or positions based on two known bearings. - The final example discusses calculating bearings between multiple points when some information about their positions is given, such as one being east of another.
