The Dancing Triangle

Move the vertices to determine the shape of your triangle and observe what happens.


Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)


  1. What do you observe when you move the three vertices?
  2. Is there a relationship between the movement of the three vertices and the area of the triangle?
  3. Move point R. What do you observe?
  4. Explain why your observation in 3 is such.

    hi. NO hosting needed. You just have to export the file to dynamic HTML, and then copy the HTML code to your blog. See the tutorials below for more info.

    1. ) Exporting GeoGebra to Dynamic HTML

    2.) Embedding a GeoGebra applet in Blogger.

    3.) More than 50 GeoGebra Tutorials

    By the way, if you are using Wordpress, it does not allow GeoGebra embedding.
