The question

Question: B is south east of A: find the bearing of B from A.

1 Draw the north line

A bearing starts at the north line.

It is measured clockwise, the way a clock turns, and written with 3 figures.

2 Measure clockwise

From north, turning clockwise to south east: 135°.

South east is a right angle and a half from north: 135°.

With 3 figures: 135°.

bearing = 135° → 135°

Careful!

A bearing always has 3 figures.

We fill with zeros in front.

Careful: not 135° ✗

3 Check

Let's check: measured from north, clockwise, with 3 figures.

So it is right!

135°: from north, clockwise, 3 figures

Let's look back.

First: draw the north line.

Then: measure clockwise.

Last: check.

Answer
Careful: not 135° ✗
