The paper discusses technology that can help students master four triangle centers -- circumcenter, incenter, orthocenter, and centroid. The technologies are a collection of web-based apps and dynamic geometry software. Through use of these technologies, multiple examples can be considered, which can lead students to generalizations about triangle centers.

Notes

Web-based apps and dynamic geometry software can help students generalize about and master circumcenters, incenters, orthocenters, and centroids.
