BEARINGS

Bearings are always measured clockwise from the north line.

1 Find the bearing of A from B. Draw a north line at B. Join B to A. A Measure the angle clockwise from the north line. B Bearing of A from B = 075o

2 Find the bearing of Q from P. Draw a north line at P. Join P to Q. Measure the angle clockwise from the north line. P Q Bearing of Q from P = 110o

3 Find the bearing of Y from X. Draw a north line at X. Join X to Y. Measure the angle clockwise from the north line. X Y Bearing of Y from X = 230o

4 The bearing of A from B is 060o. Find the bearing of B from A. N Draw a diagram to show the positions of A and B. N Draw a north line at A. Find the angle measured clockwise from the north line at A. A 60o 60o B Bearing of B from A = 180o + 60o = 240o

5 The bearing of Q from P is 250o. Find the bearing of P from Q. N N Draw a diagram to show the positions of P and Q. Draw a north line at Q. Find the angle measured clockwise from the north line at Q. 250o P 70o 70o Q Bearing of P from Q = 070o

the angles between them. N The diagram shows three straight roads connecting points A, B and C and the angles between them. N NOT TO SCALE 105o B 135o N 120o N 75o A 45o 35o C 280o a Find the bearing of C from B. Bearing of C from B = 360 – (105 + 120) = 135o b Find the bearing of A from C. Bearing of A from C = 360 – (35 + 45) = 280o
