Give reasons for your answer. (3)
| Working | Answer | Mark | Notes |
|---|---|---|---|
| 180 – 47 | 133 | 3 | M1 for 180 – 47 A1 for 133 C1 (dep on M1) for full reasons e.g. angles on a straight line add up to 180° and alternate angles are equal OR corresponding angles are equal and angles on a straight line add up to 180° OR vertically opposite angles (or vertically opposite angles) are equal and allied angles (or co-interior angles) add up to 180° |
