State the angle rule you use.
1.Two angles on a straight line are 141° and x°. Find x.
Answer: x = 39
- Angles on a straight line add to 180°
- x = 180 − 141 = 39
2.Three angles meet at a point: 47°, 88° and x°. Find x.
Answer: x = 225
- Angles at a point add to 360°
- x = 360 − 47 − 88 = 225
3.Two angles of a triangle are 25° and 104°. Find the third angle.
Answer: 51°
- Angles in a triangle add to 180°
- 180 − 25 − 104 = 51
4.Two angles on a straight line are 75° and x°. Find x.
Answer: x = 105
- Angles on a straight line add to 180°
- x = 180 − 75 = 105
5.Two angles on a straight line are 59° and x°. Find x.
Answer: x = 121
- Angles on a straight line add to 180°
- x = 180 − 59 = 121
6.Two angles of a triangle are 64° and 76°. Find the third angle.
Answer: 40°
- Angles in a triangle add to 180°
- 180 − 64 − 76 = 40
7.Three angles meet at a point: 82°, 53° and x°. Find x.
Answer: x = 225
- Angles at a point add to 360°
- x = 360 − 82 − 53 = 225
8.Three angles meet at a point: 130°, 90° and x°. Find x.
Answer: x = 140
- Angles at a point add to 360°
- x = 360 − 130 − 90 = 140
9.Two angles of a triangle are 72° and 76°. Find the third angle.
Answer: 32°
- Angles in a triangle add to 180°
- 180 − 72 − 76 = 32
10.Two angles of a triangle are 65° and 81°. Find the third angle.
Answer: 34°
- Angles in a triangle add to 180°
- 180 − 65 − 81 = 34
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.
