Chapter 8 Bearing 方位/方向
(v) Drawing a diagram to show the direction
Example:
Given the bearing of B from A is 0650. Draw the diagram of the
direction of B from A.
NN
B
650
A A
1. Draw compass direction pointing 2. Draw the bearing of B in
North at A 先在 A 画箭头指向北 clockwise direction
顺 时画出有关 B 的方位
Draw a diagram to show the direction 2. Bearing of A from B = 3300
1. Bearing of B from A = 1000
3. Bearing of F from G = 0850 4. Bearing of M from N = 2500
1. Given the bearing of B from A is 0400, find the bearing of A from B.
N
