Answer: 96°
- Angles in a triangle add to 180°
- 180 − 52 − 32 = 96
2.Two angles of a triangle are 76° and 56°. Find the third angle.
Answer: 48°
- Angles in a triangle add to 180°
- 180 − 76 − 56 = 48
3.Two angles of a triangle are 116° and 75°. Find the third angle.
Answer: -11°
- Angles in a triangle add to 180°
- 180 − 116 − 75 = -11
4.Two angles on a straight line are 35° and x°. Find x.
Answer: x = 145
- Angles on a straight line add to 180°
- x = 180 − 35 = 145
5.Two angles on a straight line are 80° and x°. Find x.
Answer: x = 100
- Angles on a straight line add to 180°
- x = 180 − 80 = 100
6.Two angles on a straight line are 32° and x°. Find x.
Answer: x = 148
- Angles on a straight line add to 180°
- x = 180 − 32 = 148
7.Two angles on a straight line are 72° and x°. Find x.
Answer: x = 108
- Angles on a straight line add to 180°
- x = 180 − 72 = 108
8.Two angles of a triangle are 104° and 60°. Find the third angle.
Answer: 16°
- Angles in a triangle add to 180°
- 180 − 104 − 60 = 16
9.Two angles on a straight line are 85° and x°. Find x.
Answer: x = 95
- Angles on a straight line add to 180°
- x = 180 − 85 = 95
10.Two angles of a triangle are 44° and 23°. Find the third angle.
Answer: 113°
- Angles in a triangle add to 180°
- 180 − 44 − 23 = 113
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.
