Note the triangle in the following figure, where **M**, **N** and **P** are the midpoints of the sides respectively. Therefore, are the medians of this triangle:

We call it *baricenter ***(G)** the intersection point of the medians of a triangle. This point divides the median relative to one side into two parts: the one from the vertex to the baricenter is twice the median from the one from the baricenter to the midpoint of the side. Look:

## Calculation of baricenter coordinates

Being **THE**(X_{THE}, Y_{THE}), **B**(X_{B}, Y_{B}) and **Ç**(X_{Ç}, Y_{Ç}) vertices of a triangle if **N** is midpoint of we have:

But:

Similarly, we determine . Like this:
