P1 Bearing Modul

  1. 1. PPR Maths nbk BEARINGS DEFINITION 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. North Examples: North a) b) North Q θ θ P P Q 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 1 Bearing of Q from P = 2 Bearing of Q from P = P=140o 050o 100o N 1400 P Q
  2. 2. PPR Maths nbk 3 Bearing of Q from P = 4 Bearing of Q from P = 5 Bearing of Q from P = 210o 330o 235o B) Based on the diagrams, state the bearing of P from Q and the bearing of Q from P Eg: N 1 N 2 N N N P N Q 65o P 75o 65o 34o Q P Q Bearing of P from Q = 180o + 65o = 245o Bearing of Q from P = 065o 3 N 4 N 5 N Q Q 65o 50o Q P P 220o P
