Bearings work by giving you a set number of degrees to turn clockwise from North.

They should always be given as three full digits (plus any decimal places) with the little degree mark.

So above you have the bearings for 026°, 147° and 243.4°.**Example:** The bearing of town b from town a is 130°. Find the bearing of town a from town b.First sketch the diagram like above.

If you look back at the rules of parallel lines you will see 130° + x° = 180° (supplementary angles rule). So x must be 50°

Therefore y° = 360° – 50° = 310°

So the bearing of town a from town b is 310°.
