11+ angles questions
Angles comes up in the maths paper of every major 11+ format. Here is what the questions look like, the method that works under time pressure, and five worked examples with the full reasoning, from a gentle start to a hard paper.
Maths · examined by GL and CEM · 5 worked examples
What your child needs to know
- Angles on a straight line add up to 180°.
- Angles in a triangle also add up to 180°. Angles all the way around a point make 360°.
Where marks get lost: Name the total first, then take away the angles you already know.
Worked examples
Every question below is generated by the same engine your child practises on, and every answer is derived by our checker rather than written by hand — which is why we can put them on a public page at all.
Example 2 · level 2 — typical of early practice
Angles on a straight line. What is the missing angle?

- 111°
- 69°
Answer: 69° — Angles on a straight line add up to 180°.
Example 4 · level 4 — a harder paper
Angles around a point. What is the missing angle?
- 218°
- -38°
- 152°
- 142°
Answer: 142° — Angles around a point add up to 360°.
Example 5 · level 5 — the level that separates candidates
Angles around a point. What is the missing angle?
- -14°
- 194°
- 166°
- 176°
Answer: 166° — Angles around a point add up to 360°.
How to practise this at home
- Work in short, frequent sessions. Ten minutes daily beats an hour at the weekend, because the recall gap is what builds memory.
- Insist on written working, even for questions your child can do in their head — under exam pressure the method is what survives.
- When an answer is wrong, ask them to explain their reasoning before you correct it. The error is almost always in one step, not the whole approach.
