WebFor integers a, b, if ab is even, then one of a, b is even. We can deduce from lemma 1 and that a2 + b2 = c2 that a + b ≡ c (mod 2). Since c ≡ − c (mod 2), we have that a + b ≡ − c (mod2). This means that 4 ∣ (a + b − c)(a + b + c) = (a + b)2 − c2 = a2 + b2 − c2 + 2ab = 2ab Since 4 ∣ 2ab, you have that 2 ∣ ab. 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
