Examples: a) b) Exercise 1 A) Based on the bearing of Q from P given, draw a diagram to show the direction of Q relative to P. Eg: Bearing of Q from P=140o 1400
P
1 Bearing of Q from P = 050o
2 Bearing of Q from P = 100o
BEARINGS
The bearing of a point P from a point Q is the angle θ measured clockwise from the north direction at Q to the
straight line joining P and Q.

EXERCISE 1 (B) ) Bearing of P from Q = 270o +15o = 285o
Bearing of Q from P = 90o + 15o = 105o 2) Bearing of P from Q = 056o Bearing of Q from P = 180o + 56o = 236o
3) Bearing of P from Q = 90o +25o = 115o
Bearing of Q from P = 270o + 25o = 295o
4) Bearing of P from Q = 180o +50o = 230o
Bearing of Q from P = 050o 5) Bearing of P from Q = 220o Bearing of Q from P = 040o
