(a) Reflect the triangle S in the line \(y = 2\). [2]
Coordinate grid, x and y from −7 to 7, with triangle S at vertices (1, 3), (1, 6) and (3, 3)
(b) Describe fully a single transformation that transforms triangle S onto triangle T. [3]
Coordinate grid, x and y from −7 to 7, with triangle S at (1, 3), (1, 6), (3, 3) and triangle T at (−3, 1), (−6, 1), (−3, 3)
(c)
(i) Translate the triangle S using the column vector \(\begin{pmatrix}-5\\-4\end{pmatrix}\). [1]
Coordinate grid, x and y from −7 to 7, with triangle S at vertices (1, 3), (1, 6) and (3, 3)
(ii) Write down the column vector that will reverse the translation in part (i). [1]
