直角三角形是一种特殊的三角形,它有许多重要的性质,其中勾股定理就是几个最重要的定理之一,它揭示了一个直角三角形三条边之间的数量关系,它可以解决许多直角三角形中的计算问题,是解直角三角形的主要依据之一,在生产生活实际中用途很大。它不仅在数学中,而且在其他自然科学中也被广泛地应用,由此我们学习勾股定理时一定要注意掌 Right triangle is a special triangle, which has many important properties. The Pythagorean theorem is one of the most important theorems. It reveals the quantitative relationship between the three sides of a right triangle. It can solve many right triangle In the calculation of the problem, is the main basis for solving the right triangle, one of the most useful in the production and life. It is widely used not only in mathematics but also in other natural sciences, whereby we must pay attention to the rules of the Pythagorean theorem
