Question 1

Pattern: Cross with 120° rotational symmetry Current: arms at: top, left, right Missing: bottom position What completes the pattern?
For 120° rotational symmetry, all positions must be filled identically. The bottom position needs the same element as the others → bottom arm.

Question 2

Pattern: Windmill with 90° rotational symmetry Current: vanes at: 0°, 120°, 240° Missing: 60° position What completes the pattern?
For 90° rotational symmetry, all positions must be filled identically. The 60° position needs the same element as the others → 60° vane.

Question 3

Pattern: Windmill with 90° rotational symmetry Current: vanes at: 0°, 120°, 240° Missing: 60° position What completes the pattern?
For 90° rotational symmetry, all positions must be filled identically. The 60° position needs the same element as the others → 60° vane.

Question 4

Pattern: Cross with 120° rotational symmetry Current: arms at: top, left, right Missing: bottom position What completes the pattern?
For 120° rotational symmetry, all positions must be filled identically. The bottom position needs the same element as the others → bottom arm.

Question 5

Pattern: Windmill with 90° rotational symmetry Current: vanes at: 0°, 120°, 240° Missing: 60° position What completes the pattern?
For 90° rotational symmetry, all positions must be filled identically. The 60° position needs the same element as the others → 60° vane.

Question 6

Pattern: Diamond with 90° rotational symmetry Current: corners filled: top, left, right Missing: bottom position What completes the pattern?
For 90° rotational symmetry, all positions must be filled identically. The bottom position needs the same element as the others → bottom corner.

Question 7

Pattern: Windmill with 90° rotational symmetry Current: vanes at: 0°, 120°, 240° Missing: 60° position What completes the pattern?
