Which one of the answer figures is the correct mirror image of the problem figure with respect to X - X ?
Show Hint
The pattern is nearly symmetric; only the two small extra lines (one vertical, one horizontal) tell the mirror image apart, so track where they go after flipping left to right.
The mirror line X - X is vertical, so left and right are interchanged while top and bottom stay the same. The square pattern is symmetric in its main lines (the outer frame, the diagonals and the inner diamond pattern), so only the small odd lines decide the answer. In the problem figure there is a short vertical line to the right of the centre, lying between the two inner diagonals, and a short horizontal line in the lower left part of the inner region. After reflection the short vertical line must lie to the left of the centre and the short horizontal line must lie in the lower right part, at the same heights as before. Option (2) shows two short vertical lines, which is wrong. Option (3) keeps the vertical line on the right and the horizontal line on the left, so it is the problem figure itself and not its mirror image. Option (4) has no short vertical line on the left. Option (1) has the vertical line on the left and the horizontal line on the lower right, so it is the mirror image. Answer: (1) Option (1) figure
