DIRECTION- 3 FIGURE BEARINGS
The main compass points, North, South, North West and so on, give us
a basic direction. If we need to describe a direction more accurately,
we can use a 3-figure bearing. This is an angle measured clockwise
from the North.
Example:
If we wanted to go from town F to town R and need to know which
direction to take, we face north at F and turn clockwise in the
direction of R. The angle we turn through is the bearing of R from F.
N

Here are more examples of bearings, all taken from F.
The bearing of A from F is 060°
The bearing of B from F is 135°

As you see, bearings are always written as 3 figure numbers, so for
example, a bearing of 40° is written as 040°.

We can also give the main compass points as 3 figure bearings.
N
Example:
NE
If we want to know the 3 figure bearing
for the compass point South East,
we face North and turn clockwise until
we reach the direction South East.
The angle we’ve turned through is: 

When we want to find other bearings, we can measure the angle of the
bearing with a protractor.

In the diagrams below, you are in town F and want to head for
town C. Try to find the bearing of C from F by measuring the
angle. (You’ll need to give the answer as a 3 figure bearing)

If the bearing is more than 180°, it may be easier to measure the
smaller angle and take that from 360°.
Example:
What is the bearing of R from F?
N
120
F
The angle between North and R is
measured as 120°. But to give the
bearing, we need the clockwise
angle (a).

So the bearing of R from F is
360° - 120° = 240°

North Lines
If you have to construct your own north line, you can use a
set square to draw a line at right angles to the top of your
paper.
Or you could try drawing a north line on acetate or transparent plastic
which can be moved around as needed.
It helps to remember, that the north line is drawn at the point you
are taking the bearing from, i.e. where you are standing.
Example:
S
We need to get from S to T.
What bearing do we need to take?
T
First draw a north line at S. Now we
can measure the bearing of T from S
The bearing of T from S is 100°

To Draw a Bearing
To draw a bearing, we need to start where the bearing is taken from
Example:
R is on a bearing of 060° from A
To find where this is, we have to begin at A and draw a north line
from A (squared paper could be used, or a set square).
N
A
Now measure an angle of 60° from A, using the north line as your
base.

When the bearing is more than 180°, you can draw the smaller anticlockwise angle as in D
