    This is THE way of "meaningful learning" which we can actually apply to our real life. Solving problems for the Pythagoras's theorem in a class room does not mean anything unless those students use the knowledge for something like this. Thank you for making the bridge.

      Yes. I remember doing pythagoras at school thinking "I'll never need to know this" - then 40 years later building my own house and learning the 3-4-5 for setting out! Now if they'd told us the 3-4-5 practical application at school I'd have been far more interested.

    It's actual new for me. That you multiplied 3*3.4*4.5*5. Oldly I used to measure feet. If long distance then I go to meter. But u made me simple. Jus multiply. It's good. I learnt something today. Thank you to share knowledge. Appreciate it.

    Jane, you are a saint. The first 2 minutes, I already understood it. I just demoed my 5'x8' bathroom and trying to square it up to build out the wall to get a bathtub in. This helped me to make a square inside the room and then see how much it's off in certain areas. I also have to tile and make sure is level, as you know this finicky detail work that takes forever is going to pay off in spades later when actually start tiling and have the bathtub in before I tile :)

    For us metric countries I adapted this to metric using leah's numbers if your tape measure is in mm only.
    So 3,4,5 feet = 300, 400, 500 mm.
    A bit bigger- = 600, 800, 1000 mm
    A bigger room can be 3,4,5 in meters :)

    I have always been taught that you simply keep doubling your numbers from 345 up to square longer footage.....6-8-10.......12-16-20......24-32-40 etc....the higher the number you go the more exact and squared up it will be. Oh! always measure form the same side of the tape thru the whole process.

    • @writerconsidered
      @writerconsidered 8 лет назад

      +Harrison Owen When I learned it in high school many moons ago it was taught as just another geometry principle. It needs to be taught as the practical geometry in the context of construction.
      I ran into this problem building a fence many years ago. I couldn't get it square to save my life so finally I went to my cousin who happens to be an engineer and he retaught me the Pythagorean theorem to get my fence straight.
      So I think for many people it is a question of relearning something especially if they haven't used that knowledge in a long time. People forget.

    • @harrison805
      @harrison805 8 лет назад

    Any suggestions on how to do this for a house that's out of square? I'm doing a remodel and the house isn't square, so not sure how to reconcile that when building laying out new interior walls. Obviously if I pull parallel off of one wall the perpendicular wall would be off a little and vice versa.

    Technically speaking you are using the Law of Cosines, not the Pythagorean Theorem. The Pythagorean theorem states that if you start with a right triangle, then the sum of the squares of the two adjacent sides will be equal to the hypotenuse squared not the other way around. Pythagoras did not say that if you have a triangle where the sum of the squares of two sides equals the square of the remaining side, then it has to be a right triangle. It's a subtle but significant difference.
