2. Bearings…
• Tell us in what direction something is
• Are more accurate than using compass
points
• Are always three figures
• Always measure the angle clockwise from
North
4. Measuring bearings…
Find the bearing of B from A.
• Mark the North line on at A
(if there isn’t a North line
draw one in)
• Draw the line connecting A
x
A to B.
• Measure the angle
x
clockwise from the North line
B to B
5. Measuring bearings…
Find the bearing of B from A.
• Place your protractor over
the north line with 0° at the
top.
• Give the answer as a three-
A
figure bearing
The bearing of B from A is 135°.

6. Measuring bearings…
Find the bearing of A from B.
• Mark the North line on at B
(if there isn’t a North line
draw one in)
• Draw the line connecting B
x
A to A.
• Measure the angle
x
clockwise from the North line
B to A
7. Measuring bearings…
Find the bearing of A from B.
• Place your protractor over
the north line with 0° at the
x
A bottom.
• Because you are measuring
x clockwise you need to
B
measure the exterior angle.
• The angle has gone past
180° so you will need to add
your measurement to 180°
8. Measuring bearings…
Find the bearing of A from B.
135 ° • The measurement from the
bottom 0° is 135°.
x
A
• 135° + 180° = 315°.
x
The bearing of A from B is 315°.
