(a) Describe the single transformation that maps triangle \(A\) to triangle \(B\). [3]
(b) Triangle \(C\) was mapped to triangle \(A\) using an enlargement, scale factor \(\dfrac{1}{3}\), centre (5, 1).
Draw triangle \(C\) on the grid above. [2]

| Rotation 90° clockwise or 270° anti-clockwise about (−1, 0) | B3 | Must be a single transformation for B3 If B3 not awarded, allow B1 for each correct ‘condition’, up to B2, from a single transformation or a multi-step transformation e.g. Award B1B1 for ‘Centre of rotation (–1, 0)’ Award B1B1 for ‘Rotation clockwise 90°, and then a translation 1 to the left and 1 down’. |
