Questions:

1) When are all the points of concurrency the same? 2) When are all the points of concurrency collinear? 3) Which point(s) of concurrency can occur in the exterior of the triangle? When does this happen? 4) Which point(s) of concurrency can occur on the sides of the triangle? When does this happen? 5) Which point(s) of concurrency can occur on the vertices of the triangle? When does this happen? 6) Is there anything else you notice? 7) Is there anything else you wonder?
