Pythagorean theorem is a basic geometric theorem. The sum of the squares of the lengths of the two right sides of a right triangle is equal to the square of the side length of the hypotenuse. That is to say, if the two right angles of a right triangle are a and B, and the hypotenuse is C, then a²+b²=c². Pythagorean theorem has been found about 400 kinds of proof methods, which is one of the most important proof methods in mathematical theorem. Zhao Shuang gave "Zhao Shuang string diagram" in the annotation of "Zhoubi Suan Jing", and proved the accuracy of Pythagorean theorem. The positive integral array (a, b, c) of the Pythagorean array with a² + b² = c² is proved. (3,4,5) is Pythagorean number.
