Triangle Inequality

Move sliders a, b and c 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 are the conditions when a triangle is formed?
  2. Explain why the three inequalities in the applet must be true for a triangle to exist.
