A line between two non-overlapping objects will always intersect exactly one of the sides of each object- you just have to pick the right one and _then_ use the intersection function.
With that said, an intersection function should probably error gracefully for parallel lines (i.e. non-intersecting).

I tried the function on two *non*-intersecting lines, and it gave me a "divide by zero" error. Not good. You need to find the mathematical intersection of the infinite lines defined by the two pairs of endpoints, and *then* decide whether or not that intersection point is within *both* of the line *segments* defined by said points.
