WebDec 6, 2015 · You are correct that A1 x + B1 y = C1 A2 x + B2 y = C2 Are parallel if and only if A1*B2 - B1*A2 == 0. Supposing that they are parallel, you want to determine whether or not they are distinct. Note that if A1*B2 - B1*A2 == 0 then there exists a constant, k, with A1*k = A2 and B1*k = B2. This constant can be computed as k = A2/A1 or k = AB/B1. WebOct 19, 2014 · If the two displacement or direction vectors are multiples of each other, the lines were parallel. If your lines are given in the "double equals" form L: x − xo a = y − yo b = z − zo c the direction vector is (a,b,c). Example: Say your lines are given by equations: L1: x −3 5 = y −1 2 = z −1 L2: x −8 −10 = y +6 −4 = z − 2 2
