The next step would be to translate the rotated rectangle over to Quadrant I. The amount to translate would depend on the dimensions of the rectangles.
whats the answer
To translate the rectangle from Quadrant III to Quadrant I, you would need to translate it by an amount equal to the distance between the origin and the y-axis (or x-axis, depending on the orientation of the rectangle).

So, you would need to translate by the values (x, y) where x and y are both positive.
