Practise vector-matrix questions by multiplying each vertex coordinate by the transformation matrix and plotting or listing the image.

The points with coordinates (1,2),(1,5) and (3,2) are the vertices of triangle A.
Hence, on the grid, draw and label triangle C.
(-2,1), (-5,1) and
(-2,3) drawn, joined
and labelled
B1 ft their answer to (c) if not plotted correctly

The single transformation that maps triangle B onto triangle C is represented by the matrix N.
State, giving a reason, the matrix N2.
Only use this grid if you need to redraw your triangles.
(1, 0
0, 1)
As reflection repeated returns any point to its original position.
B1 Matrix
B1 Reason allow for N=(1, 0
0, -1) only so N^2=(1, 0
0, -1)(1, 0
0, -1)
