TRUE BEARINGS are used to describe the direction of one object relative to another object.

The direction is described by comparing it with the true north direction.

A quick recap about degrees.

Bearings and trigonometry

When posed with a bearings problem, first draw a diagram.

Can you draw a diagram for this problem?

When Joe goes jogging he finishes 2 km south and 3 km west from where he started. Find Joe's bearing ( to 1 d.p.) from his starting point.

Did your drawing look like this?

We can now use trigonometry to find the bearing.

STEP 1: Find the angle in the triangle

STEP 2: Look for circle halves or quarters

STEP 3: Find the total bearing.
