Your picture does not contain dots. It does however have points of concurrence.
Concurrent lines (segments or rays) are lines which lie in the same plane and intersect in a single point. The point of intersection is
the point of concurrency. For example, point P is the point of concurrency.
Intersection P is the crossing of 3 segments or lines..... they all combine to make that intersection or point of concurrency.......all of the lines exist on that one point of concurrency.......
