Unit Summary

In this unit, pupils apply their knowledge of angles in order to calculate bearings and solve angle problems within the context of bearings.

Lesson Summary

You will learn to find a bearing between the points on a map or scaled plan.

Key Notes

• If the map is to scale, then you can use a protractor to measure the bearing.
• If the map is not to scale, you may need to use angle facts.
• North is always the same direction which means you have parallel lines.

Vocabulary To Learn

• 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.

Common Mistakes To Avoid

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