Question 0
B0 Worked example - no marks awarded. Demonstrates the method: reflecting in a vertical mirror line keeps the row of each shaded cell the same and swaps its column with the column the same distance on the other side of the line (column 1 becomes column 3, and vice versa). The shaded block sits in rows 1-2, column 1, so its reflection sits in rows 1-2, column 3 - option C.
Answer: C
Question 1
B1 Correct option identified (B oe, cao) - the single shaded cell reflects across the vertical line to the column the same distance on the other side, row unchanged
Answer: B
Question 2
B1 Correct option identified (D oe, cao) - the single shaded cell reflects across the horizontal line to the row the same distance on the other side, column unchanged
Answer: D
Question 3
B1 Correct option identified (A oe, cao) - both cells of the domino reflect across the vertical line to the columns the same distance on the other side, rows unchanged
Answer: A
Question 4
B1 Correct option identified (C oe, cao) - both shaded cells reflect across the horizontal line to the rows the same distance on the other side, columns unchanged
Answer: C
Question 5
B1 Correct option identified (E oe, cao) - the triangle is flipped left-right (right angle moves from the left end of the base to the right end) and its distance from the line is preserved on the opposite side
Answer: E
Question 6
B1 Correct option identified (B oe, cao) - the arrow's position flips to the opposite side of the horizontal line and the notch, which is a vertical (up/down) feature, flips from opening upward to opening downward
Answer: B
Question 7
B1 Correct option identified (D oe, cao) - the letter is flipped left-right into a backwards F and its distance from the line is preserved on the opposite side
Answer: D
Question 8
B1 Correct option identified (A oe, cao) - the whole pole-and-flag figure flips to the opposite side of the horizontal line; the flag, attached at the far end of the pole from the line, stays attached at the far end after reflection, and left-right position of the flag is unaffected by a horizontal-line reflection
Answer: A
Question 9
B1 Correct option identified (C oe, cao) - reflecting in the leading diagonal swaps the row and column numbers of the shaded cell
Answer: C
Question 10
B1 Correct option identified (E oe, cao) - the cell on the mirror line stays exactly where it is, and the other cell has its row and column numbers swapped
Answer: E
Question 11
B1 Correct option identified (B oe, cao) - every shaded cell reflects across the vertical line to the column the same distance on the other side, rows unchanged
Answer: B
Question 12
B1 Correct option identified (D oe, cao) - the cell moves to the mirror-image column and the internal diagonal split, and its shaded triangle, both flip left-right along with it
Answer: D
Question 13
B1 Correct option identified (A oe, cao) - both shapes reflect across the horizontal line to the row the same distance on the other side; the circle's appearance is unchanged by the flip since it is symmetrical
Answer: A
Question 14
B1 Correct option identified (C oe, cao) - reflecting in the anti-diagonal sends the top-left corner cell to the bottom-right corner cell
Answer: C
Question 15
B1 Correct option identified (B oe, cao) - all three cells reflect across the vertical line to the column the same distance on the other side, which reverses the direction the arrowhead points
Answer: B
Question 16
B1 Correct option identified (D oe, cao) - only a vertical line exactly midway between the two shaded cells reflects one onto the other
Answer: D
Question 17
B1 Correct option identified (A oe, cao) - only a horizontal line exactly midway between the two rows reflects one figure onto the other
Answer: A
Question 18
B1 Correct option identified (C oe, cao) - each shaded cell in the left half reflects across the vertical line to the column the same distance on the other side, rows unchanged
Answer: C
Question 19
B1 Correct option identified (E oe, cao) - every shaded cell reflects across the leading diagonal by swapping its row and column numbers
Answer: E
Question 20
B1 Correct option identified (B oe, cao) - the whole arrow flips to the opposite side of the horizontal line, keeping the same left-right direction and distance from the left end, but the hole's position within the shaft (top edge to bottom edge) flips because that is an up-down feature
Answer: B
Question 21
B1 Correct option identified (D oe, cao) - applying the vertical reflection and then the horizontal reflection in turn moves the cell diagonally to the opposite corner of the grid
Answer: D
Question 22
B1 Correct option identified (E oe, cao) - the cell reflects across the leading diagonal by swapping its row and column, and since the arrow inside it runs perpendicular to the mirror line, its line keeps the same bottom-left-to-top-right orientation but its direction reverses, so the arrowhead moves to the bottom-left end
