A bearing is three figures, clockwise from North
Always measured from North, clockwise, written with three digits (e.g. , not ).
Back bearing differs by 180°
The bearing of from is the bearing of from (add 180 if under 180, subtract if over).
Draw North lines and use parallel-line angles
Draw a North arrow at each point; co-interior (allied) angles between the parallel North lines give 180°.
Drawn from real examiner reports.
Not drawing an annotated diagram
With no diagram and no scaffolding, students don't find the angle inside the triangle to use the cosine/sine rule.
Stopping before the final bearing
Finding a distance or an interior angle but not converting it back into a three-figure bearing.
Mark every North line and angle
Annotate the diagram with North arrows and known angles before choosing a rule; give the answer as 3 figures.
