Bearings, step by step

A bearing is an angle with three rules stacked on it.

The question

Bearing of B from A?

Reading a bearing

startatnorth

turnclockwise

north=0°

bearing=000°

A bearing always starts at NORTH. Not at the horizontal, not at whichever line is drawn first — north, every time.
And it always turns CLOCKWISE. There is no counterclockwise bearing, which is why a bearing never needs a sign or a direction word.
B is north of A, and a north turn from north is 0°.
Written as a bearing that is 000° — three figures, always, so a bearing can never be mistaken for anything else.

How it works.

01
A bearing always starts at NORTH. Not at the horizontal, not at whichever line is drawn first — north, every time.
02
And it always turns CLOCKWISE. There is no counterclockwise bearing, which is why a bearing never needs a sign or a direction word.
03
B is north of A, and a north turn from north is 0°.

Written as a bearing that is 000° — three figures, always, so a bearing can never be mistaken for anything else.
