In each of the following questions, find out which of the answer figures (1),…

Concept: In a figure-matrix puzzle where a single feature (here, the cut corner of a square) shifts by a fixed rotation from one cell to the next, that rotation amount and direction are fixed by any two consecutive cells and must then apply identically to every remaining cell in every row and every column — including the missing one.

Row-wise:

1. Row 1: the cut moves from the top-left corner, to the top-right corner, to the bottom-right corner — each figure is the previous one rotated 90° clockwise.

2. Row 2: the cut moves from the top-right corner, to the bottom-right corner, to the bottom-left corner — again a 90° clockwise rotation between each consecutive pair.

3. Row 3 (known cells): the cut moves from the bottom-right corner to the bottom-left corner — the same 90° clockwise rotation.

4. Applying one more 90° clockwise rotation to the bottom-left corner of the second figure in row 3 brings the cut to the top-left corner — so the missing figure must have its cut in the top-left corner.

Cross-check: Column 3 shows the identical rule from top to bottom: the cut moves from the bottom-right corner to the bottom-left corner. Continuing that same 90° clockwise rotation for the third row lands on the top-left corner as well — the row-wise and column-wise readings agree, confirming the result independently.

Answer: The figure with the cut in the top-left corner completes the matrix.
