In the applet below, simply slide the slider very slowly and enjoy the phenomena you witness.
After doing so, feel free to adjust the

**green**and**yellow**sliders to change the sizes of the**green**and**yellow**squares, respectively. You can also change the locations of any of the white points. Interact with this applet for a few minutes. Then answer the questions that follow.Write the phenomena you've witnessed several times as a conditional ("if-then") statement.

Can you use coordinate geometry to formally prove what this applet informally illustrates? (For starters, why not let the common vertex be (0,0) and go from there?)
