| Answer | Mark | Notes |
|---|---|---|
| Shape drawn | 2 | B2 for shape with vertices at \((0, -1)\), \((-1, -3)\), \((-2, -3)\), \((-2, -1)\) (B1 for rotation of 180° about the wrong centre) |
| Answer | Mark | Notes |
|---|---|---|
| Triangle drawn | 2 | B2 for triangle with vertices at (6, 9), (9, 9), (9, 3) (B1 for 2 vertices correct or enlargement sf 3 in wrong position or enlargement, centre (0, 0), but sf \(\gt 1\), \(\neq 3\)) |
