WebbBoth Areas Must Be Equal. The area of the large square is equal to the area of the tilted square and the 4 triangles. This can be written as: (a+b) (a+b) = c 2 + 2ab. NOW, let us rearrange this to see if we can get the pythagoras … In direct proof, the conclusion is established by logically combining the axioms, definitions, and earlier theorems. For example, direct proof can be used to prove that the sum of two even integers is always even: Consider two even integers x and y. Since they are even, they can be written as x = 2a and y = 2b, respectively, for some integers a and b. Then the sum is x + y = 2a + 2b = 2(a+b). Therefore x+y h… thema liefde
