Though there are many other points of concurrency, which we will see later, we will concentrate on these four today.

IncenterPoint of concurrency formed by the intersection of the three bisectors of a triangle

CIRCUMCENTERPoint of concurrency formed by the intersection of three perpendicular bisectors of the sides of a triangle

ORTHOCENTERPoint of concurrency formed by the intersection of the three altitudes of a triangle

CentroidPoint of concurrency formed by the intersection of the three medians of a triangle

Oh yeah, in case you are wondering, here are some other more recent pts. of concurrency.Fermat PointNine-Point CenterSymmedian PointNagel PointNapolean PointSchiffler PointExeter PointApollonious PointParry PointAnd the list could go on and on and on..
