Reflect the rotated rectangle across the y-axis into Quadrant I.

Reason: a 90° rotation followed by a reflection across the y-axis is a composition of rigid motions (isometries), so it preserves distances and moves the Quadrant III rectangle onto the Quadrant I rectangle — hence they are congruent.
