Napoleon Motion!

The following applet illustrates Napoleon's Theorem without segment lengths and without angle measures. Be sure to move the BIG GRAY VERTICES of the original (white) triangle around anywhere you'd like both before and after each time you slide the slider. Without opening up another tab on your internet browser, describe Napoleon's Theorem in your own words. That is, write a conditional statement that conveys what this applet illustrates.
