Points of concurrency
From Latin: concurrere  "to run together"
The point where three or more lines intersect.
(Usually refers to various centers of a triangle).
In the figure above the three lines all intersect at the same point P  called the point of concurrency.
In relation to triangles
This concept is commonly used with the centers of triangles. Various lines drawn from a vertex of a triangle to the opposite side
happen to pass through a common point,  a point of concurrency.
