The intersection of medians of a triangle is the "center of masses" of the triangle.


It is also called "centroid" and/or "barycenter".


Very well and widely known fact is that this point has coordinates (Xc,Yc), where

Xc = %28x%5B1%5D+%2B+x%5B2%5D+%2B+x%5B3%5D%29%2F3,
Yc = %28y%5B1%5D+%2B+y%5B2%5D+%2B+y%5B3%5D%29%2F3.

In our case,  Xc = %282%2B3%2B7%29%2F3 = 12%2F3 = 4  and  Yc = %280-2%2B5%29%2F3 = 3%2F3 = 1.


So, the intersection of medians is the point (4,1).
