This is an investigation exploring medians, altitudes and perpendicular bisectors of a triangle in PDF form. Students will determine the locations of the circumcentre, orthocentre and centroid algebraically and graphically. As a final activity they will determine the Equation of the Euler line.
Student and teacher rubrics are included as well as full solutions.
