The vertices of triangle A are the points with coordinates (2,2),(3,2) and (2,4).

Triangle B is transformed to triangle C by the enlargement with centre (0,-4) and scale factor $-\frac12$ .

On the grid, draw and label triangle C.

Information for the centre/construction:
(0,-4)
or at least two construction lines through (0,-4), or one correct coordinate from:
$(2,-4),\quad(3,-4),\quad(2,-2)$
Triangle C drawn and labelled with:
$C= \begin{pmatrix} 2&3&2\\ -4&-4&-2 \end{pmatrix}$
