Choose the piece from the options that completes the figure below.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) →
The figure is symmetric about the vertical line through its centre: the right half is the mirror image of the left half. So the missing bottom-left quarter is the mirror image of the bottom-right quarter across the vertical line.
Why the other options are incorrect
Option (1) — Incorrect. This is the correct piece flipped across its middle line (its mirror image).
Option (2) — Incorrect. This is the top-left quarter turned round into the gap; the gap needs the mirror image of the quarter beside it.
Option (4) — Incorrect. The dot of the correct piece is missing.
