Here are some step-by-step ideas if you need to work with squares.
Start with your image and four rectangles on their own Layers

With the Picture Layer and first rectangle selected, you use the alignment tools under the move tool to shift to the left and up to the top

Then, with just that first move rectangle Layer selected, use the transform tool. Note that the reference point is set to the upper left corner, then rotated by -45 degrees:

One can do the same for the next rectangle to the lower left corner. Again, with the frame Layer and the second rectangle selected, with the move tool, align to the left and then down to position in the lower left corner.

With the second square Layer selected, you transform, with the reference point being the lower left corner, and rotate 45 degrees
