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 top-right quarter is the mirror image of the top-left quarter across the vertical line.
Why the other options are incorrect
Option (1) — Incorrect. This is the correct piece turned through 90° clockwise.
Option (2) — Incorrect. This copies the top-left quarter as it is; the gap needs its mirror image across the vertical line.
Option (4) — Incorrect. The dot of the correct piece is missing.
