Show answer & explanation
Correct answer: D
Mirror image is always obtained using reflection transformation. Important Points (English) A mirror image is produced using a reflection transformation .
Reflection creates a flipped image across a mirror line (axis).
The size and shape of the object remain unchanged after reflection.
Orientation changes: left becomes right and right becomes left .
The mirror line is the perpendicular bisector of the line joining a point and its image.
Reflection is an isometric transformation , so distances are preserved.
