Most of us are very familiar with the Pythagorean theorem, so familiar that we just take it for granted, but would you know how to prove it? If you would like to take a look I made a short lesson where I describe a neat proof of the theorem.

It's a hit! Over Borris's head and into left field! That'll score a run  Blue Jays up 32!

I coudda catch it...but me izz a Blue Jays fan... Btw, in 2008, my grandson's (Tyler) team (Orleans Red Sox) made it to the Nationals (senior div : ages 1516) held in Oakville, after beating the hell outta the London team in the Ontario playoff... No, we didn't win the Nationals: B.C. did. https://www.insidehalton.com/sports...altournament/ Last edited by Denis; October 25th, 2017 at 10:29 AM.
