(a) Describe fully the single transformation which maps triangle \(\mathbf{P}\) onto triangle \(\mathbf{Q}\). (3)
(b) On the grid, translate triangle \(\mathbf{Q}\) by the vector \(\begin{pmatrix} -8 \\ 2 \end{pmatrix}\)
Label the new triangle \(\mathbf{R}\). (1)
Label the new triangle \(\mathbf{R}\). (1)
(c) Describe fully the single transformation which maps triangle \(\mathbf{R}\) onto triangle \(\mathbf{P}\). (2)
| Scheme | Marks |
|---|---|
| Enlargement scale factor 3 centre (4, 3) | B3 |
| (3) |
Notes
B3: B1 for enlargement, enlarge etc
B1 for 3, ×3, three, \(\frac{3}{1}\)
B1 for (4, 3) Condone omission of brackets but do not accept \(\begin{pmatrix} 4 \\ 3 \end{pmatrix}\)
These marks are independent but award no marks if the answer is not a single transformation
| Scheme | Marks |
|---|---|
| R correct [vertices at (5, 8) (5, 14) and (2, 8)] | B1 |
| (1) |
Notes
B1: Condone omission of label
| Scheme | Marks |
|---|---|
| Enlargement scale factor \(\frac{1}{3}\) centre (8, 2) | B2 |
| (2) | |
| (6 marks) |
Notes
B2: B1 for enlargement, enlarge etc and \(\frac{1}{3}\), \(\times\frac{1}{3}\), 0.33(3….)
B1 for (8, 2) Condone omission of brackets but do not accept \(\begin{pmatrix} 8 \\ 2 \end{pmatrix}\)
These marks are independent but award no marks if the answer is not a single transformation
