Angle between two lines : equals the: angle subtended by direction vectors, s 1 and s 2 of the lines: For the lines that do not intersects, i.e., for the skew lines (such as two lines not lying on the same plane in space), assumed is the angle between lines that are parallel to given lines that intersect. First is r = (3i+2j)+t (-i+2j+k) and second is r = () + t (i+3j-k) Hence first is // (-i+2j+k) and second // (i+3j-k) So the angle between them is the same as the angle between these 2 vectors.
