# Reverse bearings

I can work out the bearing of point A from point B, given the bearing of point B from point A.

# Reverse bearings

I can work out the bearing of point A from point B, given the bearing of point B from point A.

## Lesson details

### Key learning points

- Bearings are measured from North in a clockwise direction.
- Angle facts can be used to deduce the bearing of point.
- Additional lines may be added to a diagram to facilitate problem solving.

### Common misconception

Pupils do not measure the angle from North and simply measure the angle between two line segments.

Reiterate bearings are always measured from North, in a clockwise direction and stated as 3 figures. Encourage pupils to draw North on the correct position before attempting the question.

### Keywords

Transversal - A transversal is a line, line segment, or ray that intersects through two or more lines at distinct (different) points.

Corresponding - Corresponding angles are a pair of angles at different vertices on the same side of a transversal in equivalent positions.

Alternate - Alternate angles are a pair of angles, both between or both outside two line segments, that are on opposite sides of the transversal that cuts them.

Co-interior - Co-interior angles are on the same side of the transversal line and in between the two other lines.

Bearing - A bearing is an angle measured in degrees from North in the clockwise direction and written with three figures.
