Key learning points

1. The different arrangements of 3 line segments can be described and categorised.
2. One of these arrangements involves a transversal.
3. Corresponding angles can be identified in this arrangement.
4. If the lines cut by the transversal are parallel these corresponding angles are equal.
5. Knowledge of corresponding angles can be used to find unknown angles.

Common misconception

Keywords

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

• Transversal - A transversal is any ٭line that intersects two or more ٭lines at distinct (different) points. (٭line, line segment or ray)
