Year 6 Angles Worksheet — Level 3 — Practice Set 2 — Answers
State the angle rule you use.
1.Three angles meet at a point: 52°, 144° and x°. Find x.
Answer: x = 164
- Angles at a point add to 360°
- x = 360 − 52 − 144 = 164
2.Three angles meet at a point: 115°, 93° and x°. Find x.
Answer: x = 152
- Angles at a point add to 360°
- x = 360 − 115 − 93 = 152
3.Three angles meet at a point: 101°, 104° and x°. Find x.
Answer: x = 155
- Angles at a point add to 360°
- x = 360 − 101 − 104 = 155
4.Two angles of a triangle are 107° and 119°. Find the third angle.
Answer: -46°
- Angles in a triangle add to 180°
- 180 − 107 − 119 = -46
5.Two angles on a straight line are 129° and x°. Find x.
Answer: x = 51
- Angles on a straight line add to 180°
- x = 180 − 129 = 51
6.Two angles on a straight line are 40° and x°. Find x.
Answer: x = 140
- Angles on a straight line add to 180°
- x = 180 − 40 = 140
7.Three angles meet at a point: 57°, 96° and x°. Find x.
Answer: x = 207
- Angles at a point add to 360°
- x = 360 − 57 − 96 = 207
8.Two angles of a triangle are 45° and 117°. Find the third angle.
Answer: 18°
- Angles in a triangle add to 180°
- 180 − 45 − 117 = 18
9.Three angles meet at a point: 64°, 159° and x°. Find x.
Answer: x = 137
- Angles at a point add to 360°
- x = 360 − 64 − 159 = 137
10.Two angles on a straight line are 111° and x°. Find x.
Answer: x = 69
- Angles on a straight line add to 180°
- x = 180 − 111 = 69
Marking tips
- Give credit for correct method even when the final answer slips — the working shows where the thinking went right.
- For open-ended tasks, use the success criteria as a checklist rather than looking for one "right" answer.
- Celebrate what went well first, then pick one thing to work on next.
