Dynamic Geometry: Euler Line of a Triangle. HTML5 Animation for Tablets (iPad, Nexus..) Level: High School, College, Mathematics Education

Dynamic Geometry: Euler Line
The interactive figure above, created with GeoGebra, shows a triangle ABC with the Euler Line HGO.
In a triangle ABC, the orthocenter H, centroid G, and circumcenter O always lie on a straight line, called the Euler line.

To explore (show / hide): tap a check box.
To stop/play the animation: tap the icon in the lower left corner.
To reset the interactive figure to its initial state: tap the icon in the upper right corner.
To manipulate the interactive figure: tap and drag points or lines.
