One quarter of the figure below is missing. Which option completes the figure?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) →
The figure is symmetric about the horizontal line through its centre: the bottom half is the mirror image of the top half. So the missing top-right quarter is the mirror image of the bottom-right quarter across the horizontal line.
Why the other options are incorrect
Option (2) — Incorrect. This copies the bottom-right quarter as it is; the gap needs its mirror image across the horizontal line.
Option (3) — Incorrect. This is the correct piece turned through 90° clockwise.
Option (4) — Incorrect. The black triangle of the correct piece is missing.
