Intersecting lines (Posted on 2003-07-01) Difficulty: 3 of 5
You are given two straight line segments, each defined by the coordinates of its endpoints. Segment AB goes from (Ax,Ay) to (Bx,By) and segment CD - from (Cx,Cy) to (Dx,Dy).

How would you determine if the two line segments intersect?

(Assume that you can't just draw the lines and see)

I would calculate the slope of each line using the coordinates. If the slopes of the two lines are equal, then they are parallel. If not, then they intersect.
