  2. N B N 60o Bearing of Bfrom A = 060o A • How to find a bearing: • Draw a line between the points • Draw the North line on the first point • Measure the angle clockwise from North • Write the result as 3 digits (eg 345o or 012o)

  3. N N B 180o 60o A Bearing of Afrom B = 180o+ 60o = 240o Opposite directions are always 180o apart

  4. A D B C

  5. Margin of error: Bearings should be correct to within 2 degrees ( ½ a mark for 5 degrees out) Distances need to be correct to within 5 metres ( ½ a mark for 10 metres out)

  6. How to pinpoint a location using bearings Try to work out how bearings could help you locate a ship in distress. N 360° - 275° = 85° N 058° 275° Construct the bearing from each point. Extend the lines until they cross. The crossing point is the location.
