NettetA line segment p1p2 straddles a line if point p1 lies on one side of the line and point p2 lies on the other side. A boundary case arises if p1 and p2 lies directly on the line. • Thus two line segments intersect if and only if either or both of the following conditions hold. 1. Each segment straddles the line containing other. 2. Nettet6. jan. 2024 · Identify sets of segments that lie on the same infinite line.
