2
Rules of three figure bearings
The North is the starting point and it is the 0⁰ All angles are measured from the North in a clockwise direction. All bearings are written using 3 numbers , 187⁰, 025⁰.
3
Drawing bearings The bearing of A from B is 056 ⁰. Look at the from. This means that the North is drawn from the B. Then the angle is drawn clockwise to get to A On the diagram, angles can be written without the 0 in front.
4
Similarly….. The bearing of A from B is 200⁰
5
On your mini wb, draw…… 1. The bearing of P from Q is 150⁰
6
The bearing of Y from X is 190⁰
7
Finding angles from bearings.
The bearing of B from A is 025⁰. What is the bearing of A from B ? Always remember that all arrows pointing N are parallel to each other and so angles of parallel lines ( alternate, corresponding, interior) can be used.
8
Using two or more bearings
A, B and C are three ships. The bearing of A from B is 045º. The bearing of C from A is 135º. If AB= 8km and AC= 6km, what is the bearing of B from C? Hint : In paper 1 or 2B, there will always be a right angle
9
Using 2 or more bearings ( paper 2A)
Hint : don’t set your heart on finding a 90⁰ B is 8km away from A on a bearing of 060⁰ C is 12km away from B on a bearing of 130⁰ Calculate the distance of C from A Calculate angle BAC
