WebHere are two examples of three line segments sharing a common intersection point. Line segments A C ―, D C ―, and E C ― intersecting at Point C. Line segments B D ―, C D ―, and E D ― intersecting at Point D. When dealing with problems like this, start by finding three line segments within the intersecting lines. WebRESET. An intersection is a single point where two lines meet or cross each other. In the figure above we would say that "point K is the intersection of line segments PQ and AB". Another way it may be said is that "the line segment PQ intersects AB at point K". Note that two line segments need not necessarily intersect anywhere.

Two line segments intersect

In computational geometry, the multiple line segment intersection problem supplies a list of line segments in the Euclidean plane and asks whether any two of them intersect (cross). Simple algorithms examine each pair of segments. However, if a large number of possibly intersecting segments are to be checked, this becomes increasingly inefficient since most pairs of segments are not close to one another in a typical input sequence. The most common, and m…
