Example using perpendicular distance formula (BTW - we don't really need to say 'perpendicular' because the distance from a point to a line always means the shortest distance.) Now we discuss the condition for non-intersecting lines. Spherical to Cylindrical coordinates. Also find the equation of the line of shortest distance. Ex 11.2, 15 - Find shortest distance between lines - 3D Geometry Ex 11.2, 15 (Cartesian method) Find the shortest distance between the lines ( + 1)/7 = ( + 1)/(− 6) = ( + 1)/1 and ( − 3)/1 = ( − 5)/(− 2) = ( − 7)/1 Shortest distance between two lines 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. Skipping the details, I need to find an algorithm for finding the shortest distance between three points along a line segment. In other words, it is the shortest distance between them, ... Notice that these two lines are parallel (same slope), so we can just choose a point on one of the lines, and then apply the formula. Am I right? Then, the distance between them is given by: \(d\) = \(\frac{|C_1 ~- ~C_2|}{√A^2~ +~ B^2}\) Shortest Distance Between Two parallel Lines. The formula for calculating it can be derived and expressed in several ways. The path much travel from point A to B to C. A and C are fixed points in 3D space.
