Recall each of the four centers of triangles that we have defined:

Circumcenter- The point of concurrency of the perpendicular bisectors of a triangle

Incenter- The point of concurrency of the angle bisectors of a triangle.

Centroid- The point of concurrency of the medians of a triangle

Orthocenter- The point of concurrency of the altitudes of a triangle.

Finding the coordinates of a centroid given the coordinates of the triangles vertices

Finding the coordinates of an orthocenter given the coordinates of the three vertices in a triangle

MISTAKE: x=5 is a VERTICAL line not a horizontal one.
