Practice 11 Plus Maths Angles Questions

Understanding angles for 11 plus
Angle questions are a regular feature in the 11+ maths exam. Practising these helps your child become confident with key facts and the steps needed to solve them.
Why angle practice matters
Most angle questions rely on remembering a few core rules: angles in a triangle add up to 180°, angles on a straight line add up to 180°, and angles around a point add up to 360°. Practising these rules helps children spot what to do quickly.
Worked example
If one angle in a triangle is 50°, and another is 60°, find the third angle.
Step 1: Recall that angles in a triangle add up to 180°.
Step 2: Add the two known angles: 50° + 60° = 110°.
Step 3: Subtract this total from 180° to find the missing angle: 180° - 110° = 70°.
The correct answer is 70°.
Tips for supporting your child
Encourage your child to write down the angle fact they are using for each question. Remind them not to guess by eye, as diagrams are often not drawn to scale in the test.
Key insight: Regular practice with step-by-step angle questions builds confidence and helps children apply the right rule every time, even when the diagram looks tricky.
