Problem
DO Which transformation most likely maps figure \( A B C D \) onto figure \( A^{\prime} B^{\prime} C^{\prime} D^{\prime} \) ? (A) Reflection across the \( \mathrm{Y} \)-axis (B) Rotation \( 90^{\circ} \) Clockwise about the origin about the origin
Solution
Step 1 ：Observe figures
Step 2 ：Check transformation conditions
Step 3 ：Confirm rotation
