5
(a) Describe fully the single transformation which maps shape P onto shape Q. (2)
(b) Reflect the shape Q in the line \(y = x\).
Label the new shape R. (2)
Label the new shape R. (2)
(c) Enlarge shape S with scale factor \(\dfrac{1}{2}\) and centre (1, 3) (2)
| Scheme | Marks |
|---|---|
| Reflection (in the line) \(x = 2\) | B1 B1 |
| (2) |
Notes
B1 B1: B1 for reflection, reflect, reflected
B1 for \(x = 2\)
NB: If more than one transformation then no marks can be awarded
| Scheme | Marks |
|---|---|
| Vertices at (1, −1) (4, −1) (4, −3) (3, −3) | B2 |
| (2) |
Notes
B2: B2 Shape in correct position
If not B2 then B1 for correct orientation of R but wrong position or 3 out of 4 vertices correct
| Scheme | Marks |
|---|---|
| Vertices at (3, 2) (3, 4) (4, 4) (4, 3) | B2 |
| (2) |
Notes
B2: If not B2 then B1 for shape of correct size and orientation
OR
a correct enlargement scale factor \(-\dfrac{1}{2}\), centre (1, 3)
