1.Two angles of a triangle are 111° and 113°. Find the third angle.
Answer: -44°
- Angles in a triangle add to 180°
- 180 − 111 − 113 = -44
2.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
3.Two angles of a triangle are 21° and 67°. Find the third angle.
Answer: 92°
- Angles in a triangle add to 180°
- 180 − 21 − 67 = 92
4.Two angles of a triangle are 39° and 66°. Find the third angle.
Answer: 75°
- Angles in a triangle add to 180°
- 180 − 39 − 66 = 75
5.Two angles of a triangle are 43° and 63°. Find the third angle.
Answer: 74°
- Angles in a triangle add to 180°
- 180 − 43 − 63 = 74
6.Two angles on a straight line are 56° and x°. Find x.
Answer: x = 124
- Angles on a straight line add to 180°
- x = 180 − 56 = 124
7.Two angles on a straight line are 87° and x°. Find x.
Answer: x = 93
- Angles on a straight line add to 180°
- x = 180 − 87 = 93
8.Two angles of a triangle are 70° and 101°. Find the third angle.
Answer: 9°
- Angles in a triangle add to 180°
- 180 − 70 − 101 = 9
9.Two angles on a straight line are 117° and x°. Find x.
Answer: x = 63
- Angles on a straight line add to 180°
- x = 180 − 117 = 63
10.Two angles on a straight line are 26° and x°. Find x.
Answer: x = 154
- Angles on a straight line add to 180°
- x = 180 − 26 = 154
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.
Great work. Here's what to try next:
