allerySkew lines in 3D are:
ANon-coplanar, non-parallel — cannot lie in same plane
BParallel
CIntersecting
DIdentical
Answer & Solution
Correct answer: A. Non-coplanar, non-parallel — cannot lie in same plane
**Skew lines:** not parallel AND not intersecting (don't lie in any common plane).
Unique to 3D (impossible in 2D).
Distance between skew lines = |(a₂ - a₁) · (b₁ × b₂)|/|b₁ × b₂|.
