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.
Concurrent lines
Not if they are straight lines.
In Euclidean plane geometry two infinitely long straight lines intersect at only one point
Curves yes, straight lines no
concurrent lines
Intersection
wrong!

intersection
A point where two or more lines intersect
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.
Concurrent lines
Not if they are straight lines.
its the point of concurrency
concurrent
In geometry, two or more lines are said to be concurrent if they intersect at a single point. If they do not intersect at the single point they are non concurrent.
