Altitudes
You constructed a perpendicular line. I added the perpendicular line tool. Use the tools to find the altitudes of the triangle.
Drag a corner of the triangle.The point of intersection is called the orthocenter.Is it possible for the orthocenter to be outside the triangle? If so, describe the triangle.
Is it possible for the orthocenter to be on the triangle? If so, describe the triangle and the position of the orthocenter.
