Dr. Bogomolny writ's in cut-the-knot, that he got a Proof of the pythagrean Theorem by "Mario Pacek aka Pakoslaw Gwizdalski": Whe about was this? I am interested, because I am programming visualizing such proofs and would like zu add Information about the author and the time, the proof was found. H.Friedl

In response to message #1
Thank You for your Information. Thus the proof of Mario Pacek obviously is a recent discovery. My Program showing 29 proofs of Pythagoras´ Theorem is published https://www.warwick.ac.uk/~masgaw/privateindex.html (a site of my son) Hermann Friedl
