Learn the Test
1Pick an asymmetric detail.
The flag points right of its pole. That handedness is the fingerprint.
2Rotate mentally — handedness survives.
However far you turn the figure, the flag still curls the same way around the pole.
3A flip reverses it.
In the mirror image the flag curls the OTHER way — no rotation can ever match a reflection of an asymmetric figure.

Watch Out! Common Mistakes
Looks lie! A 180° rotation and a flip can appear similar at a glance. Only the handedness test is reliable.
Useless witness! A circle or plain bar looks the same flipped or turned. Choose a part with a definite left/right character.
The classic! Upside-down ≠ mirrored. Rotate your mental image fully — if handedness holds, it’s rotation, however disorienting it looks.
⬇ Cheat Sheet
- Find an asymmetric detail — the fingerprint.
- Rotation preserves handedness (left stays left).
- Reflection reverses handedness.
- Symmetric parts can't tell you anything.

Quick summary
- Rotation turns a figure; reflection flips it over a mirror line.
- Pick an asymmetric detail and track its handedness.
- Rotations preserve handedness; reflections reverse it.
- A 180° rotation is not a reflection — check the fingerprint, not the impression.
Frequently asked questions
How can you tell a rotation from a reflection?
Track an asymmetric detail: if its left-right character survives, the figure was rotated; if it's reversed — like a hand becoming its opposite — it was reflected.
Why is 180° rotation confused with reflection?
Both make the figure look 'the wrong way up', but the handedness differs. The fingerprint test separates them instantly.
What if the figure is symmetric?
Then rotation and reflection can produce identical results — the question will always include an asymmetric detail, so find and use it.
