Question

Identify the correct mirror image of the given figure along X-X' axis :

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

The mirror X-X' is a vertical line on the right, so the image is a left-right flip: everything on the left goes to the right and diagonals reverse their slant.

Answer 1

The Correct Option is B

The mirror line X-X' is vertical, placed on the right of the figure. The mirror image is therefore the left-right reflection of the figure (top stays top, bottom stays bottom, left and right are interchanged).
Original: the top-left cell has a square cut by a diagonal running from the top-left corner; the top-right cell has a diamond; the bottom-left cell has a downward triangle; the bottom-right cell is divided into a 2 x 2 grid.
After the flip: the diamond moves to the top-left; the square with the diagonal moves to the top-right and the diagonal now runs from the top-right corner towards the centre (opposite slant); the 2 x 2 grid moves to the bottom-left; the triangle moves to the bottom-right.
Option 1 is the original figure (not flipped). Option 3 has the correct positions but the diagonal keeps the old slant. Option 4 keeps the diagonal and square in the top-left. Only option 2 matches.
Answer: (2) Option 2
