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.

The circumcentre is the basis for the sine rule.

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.
