The transformation matrix A = \begin{pmatrix}0 & -1\\1 & 0\end{pmatrix} represents a rotation of 90^\circ anticlockwise about the origin O. Matrix B = \begin{pmatrix}0 & -1\\-1 & 0\end{pmatrix} represents a reflection in the straight line y = -x.
Describe, geometrically, the transformation represented by T.
