An Anticomplementary Triangle Surprise: What Is It About?
A Mathematical Droodle

29 November 2015, Created with GeoGebra

The applet purports to demonstrate a surprising result in triangle geometry: two step Napoleon's triangle construction yields the anticomplementary triangle, i.e. the triangle formed by the straight lines passing through the reference triangle's vertices parallel to the opposite sides.
