| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| Line drawn parallel to AB, 1.8 to 2.2 cm away that meets AD and their bisector of angle BCD | M1 | Condone dotted lines throughout Use overlay as a guide If no angle bisector their horizontal line must at least touch the left hand boundary of angle bisector overlay | |
| Bisector of angle BCD drawn with correct arcs | M2 | M1 for correct bisector with no/incorrect arcs | \(\pm 2^\circ\) |
| Arc centre D with radius 2.8 to 3.2 cm | M2 | M1 for any arc centre D | Arc must meet AD and DC for 1 or 2 marks |
| Correct region shaded | A1 | Dep on M1 M1 M2 | Accept region clearly identified |
