When two lines share exactly one common point, they are called the intersecting lines. The intersecting lines share a common point. And, this common point that exists on all intersecting lines is called the point of intersection. The two non-parallel straight lines which are co-planar will have an intersection point.

How do you know if two lines intersect?

They intersect if their intersection point lies within the darker middle rectangle (i.e. the area in space that they both occupy). In other words, if the intersection point is (x,y), then x must be less than the smallest right-side value (the x-coordinate of AH here), and larger than the smallest left-side value (GB).

Are lines that intersect at a point?

When any two lines meet at one common point, they are called intersecting lines. The common point where they intersect is known as the point of intersection.
