- B. Rotational symmetry of order 4
- C. No rotational symmetry, order 1
- D. Rotational symmetry of order 8
Verified working — step 1
Each of the four curved marks is the previous one turned a quarter turn, so the tile maps onto itself every 90 degrees. 36090= …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
