| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| Triangle at (3, \(-1\)) (5, \(-1\)) (4, \(-3\)) | 2 | B1 for triangle with correct orientation and size but incorrect location | Tolerance 2mm in both parts For both parts mark to their labels unlabelled triangles score 0 |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| Triangle at (1, 1) (3, 1) (2, 3) | 2 | B1 for reflection in \(x = k\) or in \(y = -1\) | Overlay with red lines for B1 or base on the red line \(y = 1\) SC2 for 2 unlabelled triangles in correct positions |
