It was in 1765 the Swiss mathematician Leonard Euler proved that the centroid of a triangle trisects the line segment joining its circumcentre to its orthocentre. Thus the circumcentre, the centroid, and the orthocentre are collinear and form the Euler line of a triangle. The geometry features of the CAS lend themselves nicely to an investigation of the Euler line of a triangle. Starting with pen and paper, then progressing quickly to technology, this activity incorporates many aspects of coordinate geometry. No previous CAS knowledge is essential for attendees.
