Let the points on the perpendicular at which it intersects the twoOriginally Posted byfiveluck

lines be u and v. Then u and v are the points for which the distance

between points on the two lines is minimised.

So express the distance between a pair of points, one on one line

and the other on the second line, in terms of t and s, then find

the values of t and s which minimise the distance between the

two points. This will alow you to find the required points, then

you need only find the line through these two points to answer the

question.
