If 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, ... There is an important principle in algebra, that the order of operations must be observed. (a+b+c)2 requires you to perform the additions first ....

The length of X Y is a, the length of Y Z is a, and the length of X Z is c. Because triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem, a2 + b2 = c2, which in this isosceles triangle becomes a2 + a2 = c2.

The 1a | Step 3: Pythagorean Triples. A Pythagorean triple is any group of three integer values that satisfies the equation a2 + B2 = C2 is called a Pythagorean triple. therefore any triangle that has sides that form a Pythagorean triple must be a right triangle.
