Find Overlapping (intersection) point

Hello,

Is there a way to find overlapping (intersection) point for above situation.
These lines are drawn using touch, so i put a touch event listener for first line, and catch touch point.
This is not ok, because after i pass the line and i move it on other angle, i have a bad point for pivot joint.

I see that box2d puts a lighter green color for that point.
Is there a function or something to find coordinates for that point.

Thank you,
Cond0r
