- 1vec(a) × vec(b) = vec(b) × vec(c) = vec(c) × vec(a)✓
- 2vec(a) · vec(b) = vec(b) · vec(c) = vec(c) · vec(a) = 0
- 3vec(a) × vec(a) + vec(a) × vec(c) + vec(a) × vec(b) = 0
- 4vec(a) · vec(b) = vec(b) · vec(c) = vec(c) · vec(b) = 0
Correct answer
vec(a) × vec(b) = vec(b) × vec(c) = vec(c) × vec(a)
