The diagram shows a coordinate grid with triangles labelled A, B and C. The x-axis and y-axis are marked at integer values from -6 to 6. Triangle A lies in the first quadrant, triangle B lies in the fourth quadrant, and triangle C lies in the second quadrant.
(a)[2]
Describe fully the one transformation that maps triangle A onto triangle B.
(b)[3]
Describe fully the one transformation that maps triangle A onto triangle C.
(c)[2]
On the grid, draw the image of triangle A after translating by the vector $\begin{pmatrix}-2\\-3\end{pmatrix}$.
(d)[2]
On the grid, draw the image of triangle A after a rotation of $180^{\circ}$ about $(2,1)$.
