Bearings (angles) are taken towards clockwise direction from magnetic north.

Bearing are always taken from magnetic north or south whichever is nearer.

2.

Bearings are always taken in clockwise direction.

Bearings are taken in clockwise or anticlockwise direction.

3.

Bearings vary from 0° to 360°

Bearings vary from 0° to 90°

4.

Example:- 166°45́

Ex:-N 89°45́ E, N 55° W, S 69° E, S 77° W

Bearing represents measurement of angles w.r.t clockwise(examples: S 77° W or N 89°45́ E) or anticlockwise( S 69° E and N 55° W) direction or angles w.r.t north direction in surveying, where angle simply represent a degree in geometry.

How to convert reduced bearing system to whole circle bearing?

Suppose we have given N43°E means bearing is from North towards East so we do nothing i.e. 43°(WCB).—–>FIRST QUADRANT

Suppose we have given S43°E means bearing is from South towards East so we subtract from 180° i.e. 180°-43°=137°(WCB).—–>SECOND QUADRANT

Suppose we have given S43°W means bearing is from South towards West so we add 180° i.e. 180°+43°=223°(WCB).—–>THIRD QUADRANT

Suppose we have given N43°W means bearing is from North towards West so we subtract from 360° i.e. 360°-43°=317°(WCB).—–>FOURTH QUADRANT.
