  1. TRIANGLE CENTERS: POINTS OF CONCURRENCY By Mrs. Pullo

  2. Angle bisector Angle bisector bisects the angle only.

  3. Incenter • Point of concurrency formed by the intersection of the three anglebisectors of a triangle

  4. PERPENDICULAR BISECTOR Each line bisects the side and is perpendicular to the same side. It is the only line that does not Come from the vertex of the three.

  5. CIRCUMCENTER • Point of concurrency formed by the intersection of three perpendicular bisectors of the sides of a triangle

  6. ALTITUDE The altitude comes from the vertex and runs perpendicular to the side across from the vertex

  7. ORTHOCENTER • Point of concurrency formed by the intersection of the three altitudes of a triangle Orthocenter

  8. Median The median is the segment from the vertex to the midpoint of the opposite side. It is 2/3 the length of the segment From the vertex to the Centroid where all three lines intersect.

  9. Centroid • Point of concurrency formed by the intersection of the three medians of a triangle

  10. IN A NUT SHELL Median – Centroid Angle Bisector – Incenter Altitude – Orthocenter Perpendicular Bisector - Circumcenter Angle Bisector: The Incentor is equidistance to the sides Perpendicular Bisector – the Circumcenter is equidistance to the vertex
