  • You are fukcing copywriter sheet

    If you like Bertrand Russell just say it!!!

    Don't kick me MF!!!!!

  • Wisdom of the West

    Bertrand Russell (Author)

    If you don't know who is BR you are amateur

    Wish you well.

  • ohhhh.....F@#k.....hehe....yes­terday night...wile i was thinking how to proof it ....i did this.....and i was so happy!!.....(15 years old)......well....its good i that i thooght this on my own.....but it would be greater ..if i was the first who did this.........!!!....

  • @DrummerOfDust Great work if you came up with the proof independently! It's hard to come up with an entirely new proof because this particular theorem has been around for so long (thousands of years).

  • No no, it's no independent work.

    Why people just: say:

    I have seen this solution in book "Wisdom of the west" from Bertrand Russsell"

  • you just saved my math grade(: haha thanks

  • @abc12225 cool, glad you liked it!

  • Good point, Laura! The left picture does show that (a+b)² = c² + 2ab, and from there you can just use algebra to get a² + b² = c², as you show.

    The reason I drew both pictures is because I think it helps to visualize why the theorem is true. Maybe you can imagine both pictures moving together as you slightly modify the triangle. For me, proofs like this feel much more convincing most algebraic proofs -- of course, they are just as true!

  • (a + b)² = a² + 2ab + b² = (a² + b²) + 2ab = c² + 2ab

    => c² = (a² + b² + 2ab) - 2ab = (a + b)² - 2ab

    (it's all in the left drawing)

    I would like to see the proof without drawing a square because a² + b² = c² has already 3 squares!

  • pythagoras was greek!

    and i am greek!so proud of it!!!!!

  • Thank you SO much for EXPLAINING this proof. I've seen it everywhere but have NO idea how to explain it!!

    I need to do a documentary on this, and it really, really helped.

    Do you know who came up with this proof and why? Anyway, thank you very, very much.

  • Sir thank you for presenting this short but very informative proof. if you were my teacher maybe im so lucky... Im a teacher too in math here in the Philippines.. In fact this is my report now in the graduate studies to present the different proofs of Pythagorean Theorem... Thanks being the best...

  • I saw this in God Created The Integers by hawking.

  • Hey,

    That was indeed a cool proof. When you started drawing the diagram, I decided to try to complete the proof myself, and I did, but I didn't draw the second part of the diagram; insted, I used algebra. So your video was quite satisfying. Thanks.

  • Hey, glad you liked it. There are a ton of proofs of this theorem -- I chose this one because it's very easy to see as a single picture, with the two squares next to each other.

    Also, good job finishing your own proof! Nice work.

  • good stuff u dont know how many ppl u save because they hate math and u made it easy for us

  • thanks!

  • nice handwriting (:
