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.
