Orthocenter of a Triangle
- Serkan Ozel
Below you can see a triangle ABC together with its heights. The intersection point of the three heights is called orthocenter of the triangle.
- How do you construct the orthocenter of a triangle? Write down detailed construction steps on paper. Hint: You can use the arrow buttons to redo the construction.
- You can modify the shape of the triangle by dragging its vertices with the mouse. Thereby, the orthocenter and angles change too. Try to find the position of the orthocenter if a) all angles are acute. b) one angle is obtuse. c) one angle is a right angle.
