When we draw bearings, we need to remember the three main rules:
Bearings are measured from the north.
Bearings are measured clockwise.
Bearings must have three figures.
It is incredibly rare that a question on bearings will simply ask you to draw an individual bearing. Most of the questions will test you on multiple skills.
Draw a bearing of 050°
Step 1: Draw a line directly up - this is the north line that you will measure from. Label this N.
Step 2: Place your protractor on this line with the north line lined up with zero on your protractor and the numbers going clockwise.
Step 3: Measure out the angle - a bearing of 050° is 50° on your protractor.
Step 4: Draw a line for the bearing and label the angle.
B is on a bearing of 050° from A at a distance of 4 cm. C is on a bearing of 130° from B at a distance of 6 cm. Draw the bearing and measure the distance of AC.
Step 1: The first bearing is from A, so we draw a bearing of 050° from there.
Step 2: Draw another north line at B and measure the bearing of 130° from there.
Step 3: Draw a line and measure from A to C.
In this question, AC = 7.3 cm. Don’t forget that you will get a margin of error if you are measuring. In this question, you would get the marks if you measured it as between 7.1 and 7.5 cm.
B is 6 cm directly east of A. Point C is 4 cm from A and 5 cm from point B. Draw a diagram and measure the bearing of C from A.
Step 1: We know that B is 6 cm east from A; we can draw and label this:
Step 2: Use a compass to show all the points that are 4 cm from A.
Step 3: Use a compass to show all the points that are 5 cm from B. The intersection of these two lines is point C.
Step 4: Draw a north line at A and a line from A to C. Now measure the bearing.
The bearing of C from A is 033°
Now let's try some questions.
