Distance between two Parallel Lines . The distance between the start of one line and the end of the other (assuming they are both going in the same direction) could be much longer. We may derive a formula using this approach and use this formula directly to find the shortest distance between two parallel lines. Neglecting the negative sign, as the length of a segment is always positive, we have PM = |ax1+by1+c/√a2+b2|. 0 ⋮ Vote. The area of a paralellogram = p1p2/sin θ, where p1 and p2 are distances between two pairs of opposite sides and θ is the angle between any two adjacent sides. Lines in Three Dimensions. The required distance d will be PA – PB. We can then find the distance between the two lines by using the formula for the distance from a point to a nonvertical line: First, we need to take one of the line and convert it to standard form.
