Understanding angles (age 10+)
Recognise angles where they meet at a point, are on a straight line, or are vertically opposite; find missing angles using these properties
Typical age: 10–11 years
“If two straight lines cross each other, can your child tell you which pairs of angles are equal (vertically opposite) — and find a missing angle if you give them one of the others?”

Needs first
- Measuring angles (age 9+)REQUIRED
Finding missing angles extends Y5 additive angle reasoning
- Types of angles (age 8+)REQUIRED
Angles at a point, on a straight line, and vertically opposite are identified through reading standard diagram notation
- Angle Sum RulesREQUIRED
Point/straight-line/vertically-opposite angle rules build on Y5 angle-sum knowledge
