Web$\begingroup$ As it seems the OP is using "line" to mean "line segment", in the case that the slopes are different, it is also necessary to check whether the intersection occurs in … WebThe intersection of line segments algorithm is used to determine whether two line segments intersect with each other or not. The algorithm works by checking the orientation of the two line segments with respect to each other. If the orientation is different for both line segments, then they intersect. Otherwise, they do not intersect.
