Key learning points

1. Right-angled trigonometry may be useful when dealing with bearings.
2. Right-angled trigonometry can help you calculate more information.
3. Angle facts can be a simpler way of deducing information.

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.
