Triangle A is rotated \(90^\circ\) clockwise about the point (0, 1) to give triangle B.
Triangle B is translated by the vector \(\begin{pmatrix} -3 \\ -1 \end{pmatrix}\) to give triangle C.
Describe fully the single transformation that maps triangle A onto triangle C. (3)

|---|---|---|---|
| B at (1, 0), (1, \(-1\)), (3, \(-2\)) C at (\(-2\), \(-1\)), (\(-2\), \(-2\)), (0, \(-3\)) Rotation \(90^\circ\) clockwise (or \(270^\circ\) anti-clockwise) about (\(-2\), 2) | Rotation \(90^\circ\) clockwise centre (\(-2\), 2) | 3 | M2 for stating rotation \(90^\circ\) clockwise (or \(270^\circ\) anti-clockwise) or centre (\(-2\), 2) (M1 for showing B and C correctly on the grid) A1 for a fully correct description NB Award a maximum of M1 if more than one transformation is given |
