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.

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.

Bearings

{{}} are on the same side of the transversal line and in between the two parallel lines.

Using the unscaled diagram, work out the bearing from B to A.

Using the unscaled diagram, work out the bearing from A to B.

Using the unscaled diagram, work out the bearing from X to W.

Using the unscaled diagram, match the correct bearings.

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

You measure the angle with a protractor as it is a scaled drawing. 

You cannot measure the angle with a protractor as it is an unscaled drawing. 

You calculate bearings using angle facts. 

Select the correct understanding of the statement "Diagram not drawn accurately."

4 towns have been plotted on a map; A followed by B followed by C and then followed by D. They all sit on the same line segment. The bearing from A to B is 134°. What is the bearing from B to C?

Using the image, what is the bearing from X to Y?

Using the image, what is the bearing from W to Y?

Using the image, what is the bearing from X to W?
