# Bearings

## Bearings

**Bearings** are simply a way of giving directions (a bit more accurately than just relying on North, South, East and West!).

If they are given with a distance as well then you have an exact **position.**

**Note:**

**1.** Bearings are always measured from **North,** which is 000^{0} (or 360^{0}). **Always draw a North line at each point** to give a guide for your protractor.

**2.** They are always measured **clockwise** and must have **three** figures. So East is 090^{0}, South is 180^{0 }and West is 270^{0}.

If you are given the bearing and position of something **from a point** and asked to mark it in (after which you may be asked to measure something else) then here's what you do:

**1.** Draw a North line at the point you are measuring from.

**2.** Put your protractor on this point and line up 0^{0} with the North line. Always lean right over the paper when you're doing this even though you might think you look a bit stupid!

**3.** Read round the protractor **clockwise** until you reach the angle you want and mark it with a pencil.

**4. ** Draw a pencil line from the point you are measuring from right through your angle point.

**5.** Check your scale (if there is one) and measure the distance you need along this line. Put a cross to show your position.

**Don't** rub any of your pencil lines out. These help to show what you've done.

Here's the kind of diagram you might have for a ship which is 8 km away from a lighthouse on a bearing of 125^{0} using a scale of 1 cm = 1 km.

To measure the bearing of something, call it B, from something else, call it A, here's what you do:

**1.** Draw a North line at A (because that's where you're measuring **from**).

**2.** Draw a pencil line connecting A to B. This acts as a guide for your protractor!

**3. **Place your protractor on A and line up 0^{0} with the North line.

**4.** Read round clockwise until you reach the line going to B. There's your Bearing! Don't forget to write it with **three figures **(if the angle is only two digits put a zero in front!).
