Points of concurrency
Manipulate the triangle, and observe how the four points of concurrency relate.
What do you Notice? What do you Wonder?
Manipulate the triangle so that all four points of concurrency are at the same spot. What kind of triangle is this?
Manipulate the triangle so that all four points of concurrency are in a line. What kind of triangle is this?
Three of the points of concurrency are always colinear. Which are they? What does this mean?
