    To me, the most fascinating aspect is how the geometry can be represented in an equation, and how these proofs can be used to aid the construction of objects, even in ancient times, whether architecture, clothing, transportation, or whatever application was at the frontier of innovation. Even now, geometry knowledge is gold, for many careers or hobbies.

    The fact that you know something does not automatically entail you can teach the subject to people, and this is the biggest problem in many schools.
    The only way to teach something is to generate interest in the listener. Eddie has done more in a 10 minutes video that my math teacher in 5 friggin' years.

  • @GIFT19JOY23
    @GIFT19JOY23 5 лет назад +2

    Hello Teacher Eddie, i am happy in your teaching.
    We use big side as 5 (Diagonal)
    intermitted side =4 (Opposite side)
    Smaller one = 3 ( adjacent side)
    3(square) + 4(square) = 52(square)
    Sum up:
    9+16 = 25
    25=25
    tada..... tada.....

    I am sad that u r not my secondary school teacher. If u r, I will have learnt the fun of math instead of just memorising what I have been told to. Learning math should be like this, understand and apply. Too sad to say that Malaysian education has fallen behind too much, hope to see improvement in our level of teaching. Good job, Sir.

    • @neoweechang8256
      @neoweechang8256 5 лет назад

      I have been good in math, but I never realise learning math can be so fun. Yes, I did get good result in all my math exam, but basically I just memorise what I have been told to, memorise exactly what I saw in the textbook. Learning maths is more than this, understand the basic and the meaning of it is more important.

  • @od5699
    @od5699 5 лет назад

    Are you familiar with dimensional analysis Eddie? Why not also state that a rectangle is not the only shape that applies to this theorem. Semi-circles, circles, a regular pentagon, a regular decagon , a regular polygon can replace your square, in fact, it works with any similar shape. However, with diagrammatical proofs or with nines complement there is no indication as to why? Can you suss it out Eddie?

    • @official-obama
      @official-obama 3 года назад

      Simple, the area when scaled changes proportionally to the square, so the area gets multiplied by the square’s. s(a^2)+s(b^2)=s(c^2) works out to s(a^2+b^2)=s(c^2) and then we divide both sides by s to get the pythagorean theorem.
