What are bearings?

Bearings (sometimes referred to as three-figure bearings) are a way of describing and using angles.  The way they are defined means it gives us a precise location and/or direction which means they have good uses in navigation (particular of ships). 

Questions in the exam often combine this with a scale drawing so make sure you have all your maths equipment with you for the exam.

What do I need to know?

Bearings have three rules

  1. They are measured from the North direction
    North is usually straight up in terms of a scale drawing or map drawn on a piece of paper and should be shown somewhere on the diagram, looking something like this:
  2. The are measured anti-clockwise (from North)
    If you get muddled up look at a clock on the wall!
  3. The angle should always be written (said) with three figures
    So angles under 100° should have zeros to start, eg 059, 008
    Notice also that the degree symbols are not usually included when talking about bearings.
