y=-x is the diagonal line through the origin (top left to bottom right). Can you see where shape A goes when reflected in this line?

When describing rotations, you need to consider: is it clockwise or anticlockwise? what is the centre of rotation (I.e. what coordinate are you rotating it around?)

So it would be clockwise, but how do I find the centre of rotation?

The way I would do it would be to use Kelvin's constant multiplier. It combines doublet matrices to provide the two dimensional transformation. Subsequently, you times yore result by retinal convergence constant to establish equilibrium between the point of symmetry about the origin.
This sounds super confusing, do you have an example I could look at ?
