its the point of concurrency
concurrent lines are In geometry, three or more lines are said to be concurrent if they intersect at a single point.
Theorem: If two lines intersect, then exactly one plane contains both lines. So, when two or more lines intersect at one point, they lie exactly in the same plane. When two or more lines intersect at one point, their point of intersection satisfies all equations of those lines. In other words, the equations of these lines have the same solution, which is the point of intersection.
A point where two or more lines intersect
It's possible, but for any three lines in the same plane, there could be ether one point of intersection (unlikely) or three (more probably).
Perpendicular Lines are two or more lines that will intersect (come together) at some point along their paths. Paralell lines are 2 or more lines that will never intersect at any point in their paths.
Not if they are straight lines.
