14. A scalene triangle is
rotated 90° clockwise about (0, 0) then translated through \(\begin{pmatrix}4\\0\end{pmatrix}\).
Describe the single transformation that is equivalent to these 2 transformations. [3]

| Scheme | Marks | Comments |
|---|---|---|
| Rotation 90° clockwise or equivalent (about) (2, −2) | B3 | Marks can only be awarded for description of a single transformation. B2 for rotation about (2, −2) or for rotation, 90° clockwise or equivalent about ‘their (2, −2)’ provided ‘their (2, −2)’ is not (0, 0) B1 for rotation about ‘their (2, −2)’ provided ‘their (2, −2)’ is not (0, 0) If no marks award SC1 for any clear diagram showing a complete correct transformation of a triangle (which may not be scalene). |
