To show that the rectangle in Quadrant III is congruent to the rectangle in Quadrant I, Darnell rotates the first rectangle 90 degrees clockwise into Quadrant II What is his next step?

After rotating the first rectangle 90 degrees clockwise into Quadrant II, Darnell needs to perform a reflection across the y-axis to bring it into Quadrant I. This will create a congruent rectangle.

What is the answer

say the final units

After rotating the rectangle in Quadrant III 90 degrees clockwise into Quadrant II, Darnell's next step would typically be to reflect the rectangle across the y-axis to move it into Quadrant I.
