A Bearing is the amount of turn clockwise from the North direction. The amount of turn is given as an angle and in degrees.
North is shown with a vertical line. At the top of the line is either a diamond shape or the letter N.
A bearing is always given as a three-digit number. For numbers less than 100, use zeroes (0) at the front of the number to make three digits.
A bearing is described as to a point from a point; for example:
the bearing to a ship from a lighthouse is 055º
The angle is measured at the lighthouse (the from), and is the angle between North and the ship:
A reciprocal bearing is a bearing taken from the other point. A reciprocal bearing is 180º different to the original bearing.
1. What is the bearing of the lighthouse from the ship?
This is a line from the ship to the lighthouse. Measure the angle between North and the lighthouse.
Because the angle measured is anticlockwise, subtract this angle from 360º for the clockwise angle: 360 - 125 = 235º
2. What is the bearing of the plane from the airport?
Place the protractor on the airport, as this is the from location. Measure the turn, clockwise, from North. Remember to give the bearing with 3 digits in the answer.
