In the following questions, a figure is given. Choose the option that shows its mirror image, assuming the mirror is placed vertically on the left side of the figure.
Show answer & explanation
Correct answer: B
Explanation
When a mirror is placed vertically on the left of an object, a lateral inversion takes place (left and right interchange, while top and bottom remain unchanged):
• Horizontal ray: The line extending to the right with arrowheads will now extend to the left with arrowheads pointing left.
• Diagonal 1: The segment with a small circle at the bottom-left and an arrow at the top-right flips to have the circle at the bottom-right and the arrow at the top-left.
• Diagonal 2: The line with arrowheads at both ends (top-left to bottom-right) flips to run from top-right to bottom-left.
• Right-angle marker: Moves from the top-left quadrant to the top-right quadrant.
Therefore, Option (B) represents the correct mirror image.
