The question, in short
Shade one more square on the 7 by 7 grid so the completed pattern has rotational symmetry of order 4.
Summarised in our own words. Use the official paper for the exact wording and the diagram.
Solution · 1 mark
- 1Order 4 means each shaded square has matching squares at every quarter-turn about the centre square (row 4, column 4)
- 2Row 1 column 6 → row 6 column 7 → row 7 column 2 → row 2 column 1: only row 6 column 7 is missing
- 3Shade row 6, column 7
