alleryA point's reflection lies where on its perpendicular to the mirror line?
AHalf the distance
BDouble the distance
CSame distance beyond
DOn the mirror line
Answer & Solution
Correct answer: C. Same distance beyond
1. Drop a perpendicular from the point to the mirror line.
2. Extend it the same distance on the other side of the line; that end is the image.
3. The point and its image are equally far from the mirror, not half or double.
