The distance between two skew lines is naturally the shortest distance between the lines, i.e., the length of a perpendicular to both lines. The shortest distance between the lines is the distance which is perpendicular to both the lines given as compared to any other lines that joins these two skew lines. Topic 4: Vectors. What do you think is wrong with the british education system? Find the direction vector of the line you're given2. "Vectors" can be moved freely by definition, so all vectors might have the distance 0. The problem Let , and be the position vectors of the points A, B and C respectively, and L be the line passing through A and B.

(Start typing, we will pick a forum for you), Taking a break or withdrawing from your course, Maths, science and technology academic help, shortest distance between two parallel lines using vectors, Shortest distance between skew, "perpendicular" lines. If two lines are parallel, then the shortest distance between will be given by the length of the perpendicular drawn from a point on one line form another line. I.e., if $P$ is on the first line, $Q$ is on the second line, and $u$ is the normalized direction vector of one of the lines (so it has unit length), the distance between the lines is $\lVert PQ \times u \rVert$. The shortest distance between the lines is the distance which is perpendicular to both the lines given as compared to any other lines that joins these two skew lines.
