Medians and Centroid 1: Ratios of Lengths

Drag points A, B, and C to change the shape of the triangle.
As you change the shape of the triangle, what do you notice about the ratios of the lengths of the segments formed by the centroid point on each median? Explain in simple terms: if you know the length of DG, what would you do to get the length of BG? If you know the length of BD, what would you do to get the length of DG? If you know the length of AE, what would you do to get the length of AG?
