# triangle center

On every triangle there are points where special lines or circles intersect, and those points usually have very interesting geometrical properties. Such points are called *triangle centers ^{}.*

Some examples of triangle centers are incenter^{}, orthocenter^{}, centroid, circumcenter^{}, excenters, Feuerbach point, Fermat points^{}, etc.
