he first step to determine that the rectangle in Quadrant III is congruent to the rectangle in Quadrant I was to rotate the first rectangle 90 degrees clockwise about the origin. What is the next step? (1 point) translate by what?

The next step would be to translate the rectangle in Quadrant III to align it with the rectangle in Quadrant I. The translation needed would be a horizontal translation by the width of the rectangle and a vertical translation by the height of the rectangle.
