Tenth graders define the orthocenter of a triangle. In this triangles instructional activity, 10th graders draw and label a triangle shown and construct the altitudes to locate the orthocenter. Students hide the altitudes and drag the triangle to explain where the orthocenter is located for different types of triangles. Students also construct a nine-point circle for a new figure formed and compare it to the original figure.
