Class 12 Maths · Three Dimensional Geometry · Mcq Single Correct #18

Find the reflection of P(1,6,3) in the line x=(y−1)/2=(z−2)/2.

✅ Step-by-Step Solution

Final Answer: Option (C): (17/9,16/9,61/9)
  1. A=(0,1,2),d=(1,2,2). Projection parameter (P−A)·d/(d·d)=13/9. Foot H=(13/9,35/9,44/9), so 2H−P=(17/9,16/9,61/9).
