Grid with x from −5 to 9 and y from −1 to 10 showing triangle A with vertices (−4, 7), (−4, 9), (−3, 9) and triangle B with vertices (2, 5), (4, 5), (4, 4)
(a) Describe fully the single transformation that maps triangle A onto triangle B. (3)
(b) On the grid, translate triangle A by the vector \(\begin{pmatrix} 2 \\ -5 \end{pmatrix}\)
Label the new triangle C. (1)
Grid with x from −5 to 9 and y from −3 to 8 showing triangle D with vertices (0, 0), (0, 4), (2, 4) and a cross marked at (−4, 2)
(c) On the grid, enlarge triangle D with scale factor \(\dfrac{1}{2}\) and centre \((-4, 2)\) (2)
