Examples, solutions, videos, worksheets, games and activities to help Geometry students learn about the points of concurrency of a triangle - Incenter, Orthocenter, Circumcenter, Centroid.
Point of Concurrency
A point of concurrency is where three or more lines intersect in one place. Incredibly, the three angle bisectors, medians, perpendicular bisectors, and altitudes are concurrent in every triangle. There are four types important to the study of triangles:
for angle bisectors, the incenter;
for perpendicular bisectors, the orthocenter;
for the altitudes, the circumcenter;
for medians, the centroid.
