Incenter of a Triangle | Formula, Properties and Examples In geometry, a triangle center (or triangle centre) is a point in the plane that is in some sense a center of a triangle akin to the centers of squares and circles, that is, a point that is in the middle of the figure by some measure.For example, the centroid, circumcenter, incenter and orthocenter were familiar to the ancient Greeks, and can be obtained by simple constructions. Orthocenter: Where the triangle’s three altitudes intersect. The distance between the centroid and the orthocenter is always twice the distance between the centroid and the circumcenter. Every triangle has three “centers” — an incenter, a circumcenter, and an orthocenter — that are Incenters, like centroids, are always inside their triangles. The word middle was thrown out constantly and I regularly had to ask for clarification- what kind of middle? The incenter can be constructed as the intersection of angle bisectors.It is also the interior point for which distances to the sides of the triangle are equal. centroid.
