Did Thales have anything to do with the Pythagorean Theorem?

While the historical record is unclear about precise influences, it seems likely that Thales of Miletus (circa 620-546 BC/BCE) had some impact on the thinking of the apparent discoverer of the Pythagorean Theorem, namely, Pythagoras (circa 570-495). Given the prestige of Thales in his day, along with his own careful research into mathematical theorems, it is reasonable to conclude that Pythagoras was inspired, and perhaps much more, by the mathematical work of Thales.
