A coordinate plane showing three shaded rectangles.
The 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?

Answer 1

Reflect the rotated rectangle across the y‑axis (the line x = 0).

Algebraically: rotate 90° clockwise (x,y) → (y,−x), then reflect across the y‑axis → (−y,−x). For points in Quadrant III (x<0,y<0) this gives (−y,−x) with both coordinates positive, placing the rectangle in Quadrant I.
