    Given two straight lines, the Pythagorean Theorem allows you to calculate the length of the diagonal connecting them. This application is frequently used in architecture, woodworking, or other physical construction projects. For instance, say you are building a sloped roof.

      @@rcknross Any logic or evidence to support that claim?
      For example, you know that "Dean Jelbert Austria" was taught in America? And had a teacher using Common Core?
      Or some reason anyone should believe YOU that "common core" dictates how specifically a teacher teaches a subject -- DESPITE the fact that ALL the documents describing it, those who created it, and those who use it, have explained over and over again that it does NOT do that?
      Or that there is reason to believe students taught prior to common core would be LESS likely to describe their teacher as "blabbering in front of the class"?
      Or a way you have taken into account, and made allowances for, the difference in audience? There's a HUGE difference between (i) a student self-motivated enough to watch a math video, and having the ability to start and stop it or repeat sections if they like, and (ii) a teacher who does not have the luxury of teaching each student individually, nor is blessed with a classroom of students with Dean's level of commitment to learning.

      @benjaminpinney8509 2 роки тому

      (a+b)² → (a+b)(a+b) → a²+ab+ab+b² → a²+2ab+b². So... It's because of distribution. Is that what you were asking about?

  • @ajvarninja415
    @ajvarninja415 5 років тому +2

    I prefer trigonometry as it is way quicker:
    Sinx = b/c
    Cosx = a/c
    Now we square them and get
    Sin²x = b²/c²
    Cos²x = a²/c²
    Then we add the equations and get
    Sin²x + cos²x = a²+b² / c²
    Using the property that sin² + cos² =1,
    We get
    1 = a² + b² / c²
    Now we multiply both sides by c² and get
    C² = a² + b²

    Very nice explanation. It can also be proved by similar triangles.
    One of the practical proofs i came across at a Science Centre -- what they did was they created right triangle and on each of the sides built a squared box having same depth. And filled the box over hypotenuse completely with a coloured liquid. The system was mounted and could b rotated. The boxes were imterconnected. On rotating the system upside down, they showed that the liquid in the hypotenuse box got completely filled in the other two boxes. Of course, a2 * d + b2 *d = c2 * d. i. e. Equating the volumes. The depth d cancels out n we see the pythagoras theorem is proved.

    En cuanto al Triángulo rectángulo, donde se aplica el "Teorema de Pitágoras", tengo un nuevo concepto sobre este "Teorema" voy a llamar "Teorema de Sidney Silva" sigue mi relato;
    Condición de Existencia de un Triángulo; para construir un triángulo no podemos utilizar ninguna medida, tiene que seguir la condición de existencia: Para construir un triángulo es necesario que la medida de cualquiera de los lados sea menor que la suma de las medidas de los otros dos y mayor que el valor absoluto de la diferencia entre estas medidas, esto está relacionado en el Teorema de Pitágoras, ya en el "Teorema de Sidney Silva" podemos sí utilizar cualquier medida, siguiendo la condición de existencia; donde puedo construir un Triángulo que la necesidad de la medida de cualquiera de los lados sea mayor que la división de las medidas del lado más pequeño del valor absoluto (fórmula a ^ 2 = b ^ 2: c ^ 2 o b ^ 2: c ^ 2 En el caso de la hipotenusa será menor que los catetos, y siempre los catetos serán mayores que la Hipotenusa, donde los números 5,4,3 ya están obsoletos, cuando cambien de números, será aproximado , redondeado y simplificado, ya por mi "Teorema de Sidney Silva" siempre será exacto con 100% exactos .. !!!!, Sr Sidney Silva.

    According to with your definitions, c square is the area of the INNER triangle. Summed to the areas of the 4 triangles equals the OUTER triangle's area. Even with this tiny detail, I can say this is one of the best explanations I have ever found because it inks nicely the quadratic equation with the basics of trigonometry.
