WebAC 2 +BC 2 = AB(BD+ AD) = AB2. Therefore, AC^2 + BC^2 = AB^2. \ _\square AC 2 +BC 2 = AB2. Algebraic Proofs Two Algebraic Proofs using 4 Sets of Triangles The theorem can be proved algebraically using four copies of a right triangle with sides a a, b, b, and c c arranged inside a square with side c, c, as in the top half of the diagram. WebIf a+ b+ c = 0 and a2 + b2 + c2 = ab +bc +ac, then it follows that 0 = (a+ b+ c)2 = a2 +b2 +c2 +2(ab+ bc +ac), or a2 +b2 +c2 = −2(ab +bc +ac). Put this together and we will see that in fact a2 + b2 + c2 = 0, ... Vertices of equilateral triangle on complex plane
