勾股定理的由来:勾股定理也叫商高定理,在西方称为毕达哥拉斯定理.我国古代把直角三角形中较短的直角边称为勾,较长的直角边称为股,斜边称为弦.勾股定理为:两直角边的平方和等于斜边的平方表示方法:如果直角三角形的两直角边分别为a,b,斜边为c,那么勾股定理是初中数学,重要的一部分,在实际中如果能巧妙的运用勾股定理,会极大提高学生学习数学的乐趣。
Pythagorean theorem origin: Pythagorean theorem also called the business of high theorem, in the west called Pythagorean theorem.In ancient China, the shorter right-angled triangle in right-angled triangle is called hook, the longer right-angled side is called stock, The hypotenuse is called a chord. Pythagorean theorem is that the sum of the squares of the two right-angled edges is equal to the square of the hypotenuse. If the two right-angled edges of the right-angled triangle are a, b, and the hypotenuse is c, then the Pythagorean theorem is the junior high school mathematics The important part is that in practice, if you can skillfully use the Pythagorean theorem, you will greatly enhance the fun of learning mathematics.
