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?

Then apply the rotation to G.

Thank you, for this would the scale factor be 2 and the centre of enlargement be (5,2) ?

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?
Just googled it and it says I need a compass but I don't own a compass is there another way I can do it?
Anyone ?

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 ?
