One use of a centroid is that it tells you the location of the triangle's centre of mass, if the mass is of uniform density.

Hi;

There are many, many more. For instance, the famous Fermat - Torricelli point.

### Re: centroids

Hi;

This is the complete list of them, they are difficult because they are in terms of barycentric coordinates but you will get an idea of how many there are.
