Answer: Are parallel (lie along the same or parallel lines).
- A Have exactly the same magnitude but any direction
- B Are perpendicular, meeting at a right angle
- C Have zero magnitude, making them null vectors
- D Are parallel (lie along the same or parallel lines)
Correct answer: D. Are parallel (lie along the same or parallel lines)
Explanation: Collinear vectors lie along the same line or parallel lines. One is a scalar multiple of the other.
Triangle law of vector addition: placing vector b at the head of vector a, the diagonal from the start to the final head gives the resultant a + b.
