Given a point a line and want to find their distance. Before we proceed towards the shortest distance between two lines, we first try to find out the distance formula for two points. 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. On signing up you are confirming that you have read and agree to A similar geometric approach was used by [Teller, 2000], but he used a cross product which restricts his method to 3D space whereas our method works in any dimension. d = | (\vec {a}_2 – \vec {a}_1) . A line parallel to Vector (p,q,r) through Point (a,b,c) is expressed with.

d = ∣ ( a ⃗ 2 – a ⃗ 1). Also, the solution given here and the Eberly result are faster than … We first need to normalize the line vector (let us call it ).Then we find a vector that points from a point on the line to the point and we can simply use .Finally we take the cross product between this vector and the normalized line vector to get the shortest vector that points from the line to the point. Therefore, two parallel lines can be taken in the form y = mx + c1… (1) and y = mx + c2… (2) Line (1) will intersect x-axis at the point A (–c1/m, 0) as shown in figure. Now,
