Hint 3 of 3
Flip each row so the left square becomes the right square, then find the matching picture.
Show solution
Approach: flip the pattern left-to-right like a mirror
- Looking from outside is like seeing the window through a mirror, so the picture flips left-to-right.
- Take each row and swap its left and right squares: the black square on the left jumps to the right, and so on.
- The flipped pattern matches option D.
