6
(a) Describe fully the single transformation which maps triangle \(\mathbf{P}\) onto triangle \(\mathbf{Q}\). (2)
(b) Describe fully the single transformation which maps triangle \(\mathbf{P}\) onto triangle \(\mathbf{R}\). (3)
| Scheme | Marks |
|---|---|
| Reflection in the line \(y = 4\) | B2 |
| (2) |
Notes
B2: B1 for reflection, reflects etc.
B1 for \(y = 4\) or eg ‘dotted line’ but, if given, equation must be correct
| Scheme | Marks |
|---|---|
| Enlargement with scale factor \(1\frac{1}{2}\), centre (1, 6) | B3 |
| (3) | |
| (5 marks) |
Notes
B3: B1 for enlargement, enlarge etc.
B1 for \(1\frac{1}{2}\) oe
B1 for (1, 6)
These marks are independent but award no marks if answer is not a single transformation. (Second transformation may be implied)
