, , Line passing through the point B(a2,b2,c2) parallel to the vector V2(p2,q2,r2). , , Please enter the values for vector V2 : , , Shortest distance between two lines(d). We are considering the two line in space as line1 and line2.
the distance between 2 lines is defined as the perpendicular distance between them. thus this is only applicable to parallel lines because if 2 lines are not parallel, there will be no line that cuts the two lines The question of distance between two straight lines arises only when they are parallel.
Directed line segments AB are introduced as three–dimensional column vectors: If A = (x1, y1, z1) and B = (x2, y2, z2), then AB= x2 −x1 y2 −y1 z2 −z1 . If P is a point, we let P= OP and call P the position vector of P. With suitable deﬁnitions of lines, parallel lines, there are important ge-
