Triangle Medians Help

This is HELP for the Exploring InterActivity on Triangle Medians construction.

1)  Step 1: Understand the problem

Goal:  Construct a triangle given its three medians t_a, t_b and t_c. Base your construction on the definition of the median and the fact that the three medians of a triangle meet at a single point T and T is 2/3 of the way along each of the medians. (T is called the centroid.)

From the definition of “median”, it follows that one endpoint of a median is a vertex of the triangle and the other is the midpoint of the opposite side.
