Which are possible relationships between two distinct planes in ℝ³?
Hints
- Picture two flat sheets and ask how they can meet.
- Sheets are too large to touch at only one spot.
Show the answer
- A. Identical
- B. Parallel (no intersection)
- D. Intersect in a line
Why
Two distinct planes in ℝ³ are either parallel or intersect along a line, never at a single point.
