1.30 Centroid Warm-Up

All three medians of a triangle will intersect at the same point - the centroid. Move the points of the triangle to see how the centroid changes. The centroid is the "center of gravity" for a triangle - a triangle can balance on its centroid.

 How would you define a median based on the black segments shown?

 What do you observe about the lengths of the medians compared to other lengths?
