The points of concurrency are marked and color coded.[br][br]Drag the vertices of the triangle and observe how the points of concurrency move. Use your observations to answer the questions below.

[br][br]1) Classify the triangle (using side lengths )when all the points of concurrency are the same.[br][br]2) Classify the triangle (using side lengths )when all the points of concurrency are colinnear.[br][br]3) Which point(s) of concurrency can occur in the exterior of the triangle? Classify the triangle (using angle measure) where the points of concurrency are in the exterior.[br][br]4) Which point(s) of concurrency can occur on the sides of the triangle? Classify the triangle (using angle measures) where the points of concurrency are on the sides.[br][br]5) Which point(s) of concurrency can occur on the vertices of the triangle? Classify the triangle.
