A line passes through the points A(1, 2, 3) and B(4, 5, 6). Another line passes through C(1, 0, 1) and D(2, 1, 2). The angle between them is: A. 0° B. 30° C. 45° D. 60° Answer: A) 0° Explanation: DRs of AB are 3, 3, 3 (or 1, 1, 1). DRs of CD are 1, 1, 1. Since their DRs are proportional, they are parallel, so the angle is 0°.
