definition of intersecting lines​

Answer 1

$\Huge\mathcal{\fcolorbox{red}{cyan}{\red{Answer}}}$

In Euclidean geometry, the intersection of a line and a line can be the empty set, a point, or a line. Distinguishing these cases and finding the intersection point have use, for example, in computer graphics, motion planning, and collision detection.

Two or more lines which share exactly one common point are called intersecting lines. This common point exists on all these lines and is called the point of intersection.
