Triangle Centers Points of Concurrency
• What is this all about?A Point of Concurrency is a point
of intersection of 2 or more lines. The lines that form a point
concurrency are called concurrent lines.
The Points are…The Points are…
• Incenter• Circumcenter• Orthocenter• Centroid
• Though there are many other points of concurrency, which we will see later, we will concentrate on these four today.
Incenter• Point of concurrency formed by the
intersection of the three bisectors of a triangle
CIRCUMCENTERCIRCUMCENTER• Point of concurrency formed by the
intersection of three perpendicular bisectors of the sides of a triangle
ORTHOCENTER• Point of concurrency formed by the
intersection of the three altitudes of a triangle
Centroid• Point 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 Point• Nine-Point Center• Symmedian Point• Nagel Point• Napolean Point• Schiffler Point• Exeter Point• Apollonious Point• Parry Point• And the list could go on and on and on…..
