Follow one thing on paper: what you see, where it goes after a turn or a flip, where a face lands when folded. Don't turn the whole shape in your head.

One flip swaps one pair
When to use it: A whole picture is flipped and the question asks what it looks like now: reflected in a vertical or horizontal line once or several times, seen through glass from the other side, printed by a stamp, or a clock in a mirror.
- Flip over an vertical line: left and right swap. Flip over a horizontal line: top and bottom swap. One flip swaps one pair.
- If the line isn't given, see which way the positions swapped in the options, or how the person stands.
- The pair that doesn't swap keeps its direction too.
- Two flips over the same line cancel out.
