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

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

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

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

Finding a bearing

Maths

In the angles unit, pupils reasoned through more complex problems involving angles. In the bearings unit, pupils apply their knowledge of angles in order to calculate bearings and solve angle problems within the context of bearings.
