What are bearings?Bearings are simply a way of giving directions.

They are more accurate than saying North, or East, or South, or West.

If provided with a distance then you can find the exact location.

Note:1. Bearings are always measured from North, which is 000° (or 360°).

Draw a line North for each point you are working with.

2. Bearings are measured clockwise and must have 3 figures.
