Lesson details
Key learning points
- Angles that meet at a point can be identified in diagrams.
- Angles that make a straight line can be identified on a diagram.
- Vertically opposite angles can be identified on a diagram.
Keywords
Supplementary angles - Supplementary angles are a pair of angles that sum to 180°.
Conjugate angles - Conjugate angles are a pair of angles that sum to 360°.
Common misconception
In order for two angles to be supplementary, they must both lie about a point on a straight line.
For two angles to be supplementary, they must sum to 180°. They do not also need to both lie on a straight line.
