在平面直角坐标系中,不同三角形的证明都是在长度的基础上实现的,完成了用计算方法证明平面几何的思想设定。本文以示例的形式展示了以抛物线为背景的特殊三角形问题的解决方法,希望可以抛砖引玉。1抛物线中的直角三角形在初中数学中,提起直角三角形用得最多的就是勾股定理,这是初中阶段证明直角三角形最有效的方法,也是直角三角形最重要的性质。学生对于勾股定 In the Cartesian coordinate system, the proof of different triangles is realized on the basis of the length, and the thought setting of plane geometry proved by calculation is completed. This article shows an example of the solution to the problem of a special triangle with a parabola as a backdrop, hoping to start a discussion. 1 right triangle in the parabola In junior high school mathematics, the most commonly used to lift the right triangle is the Pythagorean theorem, which is the most effective way to prove the right triangle in the junior middle school, but also the most important property of the right triangle. Students for the Pythagorean fixed
