Question 0
B0 Worked example - no marks awarded. Demonstrates the method: track where the right-angle corner (marked with the dot) moves under a 90 degree clockwise turn - bottom-left moves to top-left - then redraw the two short edges meeting at that corner and the bold hypotenuse joining the two corners not touched by the dot.
Answer: B
Question 1
B1 Correct option identified (A oe) - an arrow pointing up, rotated 90 degrees clockwise, points right
Answer: A
Question 2
B1 Correct option identified (D oe) - after a 180 degree turn the letter is upside down: the arm-end moves from top to bottom and the arms now point left instead of right
Answer: D
Question 3
B1 Correct option identified (A oe) - a mouth opening right, rotated 90 degrees clockwise, opens downward
Answer: A
Question 4
B1 Correct option identified (B oe) - the notch moves from the right edge to the bottom edge, and the stripe order reverses (grey, white, black) once the stripes become vertical
Answer: B
Question 5
B1 Correct option identified (B oe) - the long edge moves from the bottom to the left-hand side, and the diagonal now runs from the new top-left corner to the new bottom-right corner
Answer: B
Question 6
B1 Correct option identified (C oe) - continuing the 90 degree clockwise step from Panel 3 moves the long edge to the right and the diagonal to top-left/bottom-right
Answer: C
Question 7
B1 Correct option identified (A oe) - after 180 degrees the flat edge moves to the top (bulge hangs below) and the notch, which was near the left end, is now near the right end of that edge
Answer: A
Question 8
B1 Correct option identified (C oe) - a tip pointing left, rotated 90 degrees clockwise the same way Shape 1 became Shape 2, points up
Answer: C
Question 9
B1 Correct option identified (E oe) - this combination (arm-end left, arms pointing down) does not occur at any 90, 180 or 270 degree rotation of the tile; it can only be produced by reflecting the shape
Answer: E
Question 10
B1 Correct option identified (B oe) - after a 270 degree clockwise turn the dot-square moves from above the corner to the left of it, and the grey square moves from the right of the corner to above it
Answer: B
Question 11
B1 Correct option identified (A oe) - the arrow's corner moves from top-left to top-right, and its pointing direction rotates from south-east to south-west, keeping it pointed at the centre
Answer: A
Question 12
B1 Correct option identified (B oe) - a black point on the right, rotated 90 degrees anticlockwise the same way Shape 1 became Shape 2, moves to the top
Answer: B
Question 13
B1 Correct option identified (A oe) - the notch moves from the left edge to the right edge, and the stripe order reverses top to bottom (grey, white, black), while the rectangle stays tall since 180 degrees does not change tall to wide
Answer: A
Question 14
B1 Correct option identified (C oe) - the notch position (left-hand edge) matches the genuine 180 degree rotation, but the stripe order has not been reversed, which only happens if the flag is mirror-imaged rather than rotated
Answer: C
Question 15
B1 Correct option identified (B oe) - continuing the 45 degree clockwise step from Panel 3 (mouth down) moves the mouth to the lower-left
Answer: B
Question 16
B1 Correct option identified (C oe) - after a 90 degree anticlockwise turn the grey square moves from above the corner to the left of it, and the dot-square moves from the right of the corner to above it
Answer: C
Question 17
B1 Correct option identified (A oe) - the arrow's corner moves from top-left to bottom-right (two steps of the corner cycle), and its pointing direction rotates from south-east to north-west, keeping it pointed at the centre
Answer: A
Question 18
B1 Correct option identified (C oe) - applying the same 90 degree clockwise rule to Shape 3 moves the dot-square from below the corner to the left, and the grey square from the left of the corner to above it
Answer: C
Question 19
B1 Correct option identified (C oe) - 135 degrees clockwise (three 45 degree steps) moves the stroke onto the upper-left to lower-right diagonal, with the arm-end at the lower-right and the arms pointing toward the lower-left
Answer: C
Question 20
B1 Correct option identified (B oe) - two successive 90 degree clockwise turns (180 degrees total) send the column from pointing up to pointing down and the single grey square from the right of the corner to the left, with the dot staying on the far square of the column
Answer: B
Question 21
B1 Correct option identified (C oe) - both the arrow and the flag must rotate together by the same 45 degree anticlockwise amount, from up to upper-left, and from right to upper-right
Answer: C
Question 22
B1 Correct option identified (C oe) - up, right, down and left are all related to each other by exact multiples of 90 degrees, but upper-right is offset by only 45 degrees from up, so it does not belong to that family
