I'd like to verify my solutions for Q8, 12, 17, 18 and 31. In particular, I haven't utilised all the information in each of these puzzles below and want a better explanation for these.
C, Seems like column 2 and 3 are just plain reflection in the x-axis, but then the information in column 1 doesn't mean anything? What does it do?
(Approach 1) A, See each row, clockwise rotation, 2 black 1 grey. (Approach 2) D, See SW diagonal line. 2 identical shapes, 1 rotated shape. Grey rotates clockwise, black anti-clockwise.
F, tangent to the line in column 1 is the acute reflection Axis for col 2 and 3.
C, col-wise + symbol represents 90 deg rotation. Row-wise col 1 and 2 is addition operation. Unsure how the shapes are arranged in col 3. But since row 3 is 90 deg rotation to row 1, I guessed C.
I have seen this question discussed in more detail here: Duplication Question But
I'd be happy with D If it wasn't Black + Black = White or Stripe (So, not a function) Since then you can just argue the same for other colours. i.e. W + S = B or W or S. There is insufficient information in this problem, I think A is also a possibility.. At least 3 whites and 3 Stripes are there too and 3 blacks would still make a pattern.
Many thanks in advance.
