The Euler Line

In the figure below, the green, red, and violet 'points' are the orthocenter, centroid, and circumcenter of triangle ABC respectively. Move the points A, B, and C and notice what happens. Use these points to create different types of triangles. What do you observe? This is a Java Applet created using GeoGebra from - it looks like you don't have Java installed, please go to
The blue line above is called the Euler line. The Euler line passes through the three important points determine by a non-equilateral triangle. It also passes through the center of the nine point circle.
