how do we find bearing of points for example point g with diagrams
Answers
Bearings
A directional compass is shown below. It is used to find a direction or bearing .
A compass with markings at 10 degree intervals
The four main directions of a compass are known as cardinal points. They are north (N), east (E), south (S) and west (W). Sometimes, the half-cardinal points of north-east (NE), north-west (NW), south-east (SE) and south-west (SW) are shown on the compass. The above compass shows degree measurements from 0° to 360° in 10° intervals with:
north representing 0° or 360°
east representing 90°
south representing 180°
west representing 270°
When using a directional compass, hold the compass so that the point marked north points directly away from you. Note that the magnetic needle always points to the north.
Bearing
The true bearing to a point is the angle measured in degrees in a clockwise direction from the north line. We will refer to the true bearing simply as the bearing.
The bearing or true bearing of P and Q is shown
For example, the bearing of point P is 065º which is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the centre of the compass at O with the point P (i.e. OP).
The bearing of point Q is 300º which is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the centre of the compass at O with the point Q (i.e. OQ).
Note:
The bearing of a point is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the centre of the compass with the point.
A bearing is used to represent the direction of one point relative to another point.
For example, the bearing of A from B is 065º. The bearing of B from A is 245º.
The relative bearings of A and B are shown
Note:
Three figures are used to give bearings.
All bearings are measured in a horizontal plane.
