Today's lesson is designed for the students to construct the four centers of a given triangle.

The student handout is designed to be used with The Geometer's Sketchpad.

The four centers are as follows:

Centroid: The intersection of the medians.

Incenter: The intersection of the angle bisectors.

Circumcenter: The intersection of the perpendicular bisectors.

Orthocenter: The intersection of the altitudes.
