12
(a) Describe fully the single transformation that maps triangle A onto triangle B (2)
(b) On the grid above, enlarge triangle A with scale factor 2 and centre \(O\)
Label your triangle C (2)
Label your triangle C (2)
| Scheme | Marks |
|---|---|
| Reflection | B1 |
| \(x = -1\) | B1 |
| (2) |
Notes
B1: for reflection with no mention of translate, enlarge, rotate, move
B1: for \(x = -1\) with no mention of a vector, SF, centre or angle
| Scheme | Marks |
|---|---|
| Triangle drawn with vertices at (4, 2) (4, 8) (8, 2) | B2 |
| (2) | |
| (4 marks) |
Notes
B2: for a correct enlargement
(B1 for an enlarged triangle scale factor 2 in wrong position or 2 out of out 3 vertices in the correct position)
