The points of Concurrency are marked and color coded.

Drag the vertices of the triangle and observe how the points of concurrency move. 1) Describe the shape of the triangle when all the points of concurrency are the same. 2) Describe the shape of the triangle when all the points of concrrency are colinnear. 3) Which point(s) of concurrency can occur in the exterior of the triangle? 4) Which point(s) of concurrency can occur on the sides of the triangle? 5) Which point(s) of concurrency can occur on the vertices of the triangle?
