A mirror lies along the horizontal line MN under the figure. Choose the image of the figure formed in it.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →
A horizontal mirror line (water image) turns top into bottom but keeps left and right: every part moves to the opposite height on the same side and is turned upside down.
Option (1) — Incorrect. The arrow is in the right place but is not turned over: it still faces the same way as in the question figure.
Option (2) — Incorrect. This is the image in a vertical mirror: the figure is turned left to right instead of upside down.
Option (3) — Incorrect. This is the figure turned through 180° (half a turn): it is flipped both left to right and top to bottom.
