Basic Orthocenter, Mid-Segment Triangle
To create the triangle, right click once and drag to create the base in any desired direction. The move up (or down) to create the peak of the triangle. You have now created a mid-segment triangle. Notice that both the larger and the smaller triangles will have an orthocenter. You can also play with the one I have already created to see what happens to both triangles as the size changes. Enjoy!
