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.

... I have a small favor to ask. Over the years we have used advertising to support the site so it can remain free for everyone.
However, advertising revenue is falling and I have always hated the ads. So, would you go to Patreon and become a patron of the site?
When we reach the goal I will remove all advertising from the site.
It only takes a minute and any amount would be greatly appreciated.
Thank you for considering it! – John Page
