在图形运动的过程中,由三个点为顶点的图形若为直角三角形,一般可以讨论这个三角形的三条边是否满足勾股定理逆定理所需的条件.一、直角三角形的勾股定理以及它的逆定理是解这部分题目的重要依据.三角形的存在性,即两边和大于第三边,是解这部分题目的首要条件,一个三角形有三个角,这三个角都有可能成为直角,所以在做
In the process of graphics movement, the vertices of the three vertices if the graph is a right-angled triangle, the general can discuss whether the three sides of the triangle meet the Pythagorean theorem inverse theorem required conditions. First, the right triangle Pythagorean theorem and it Of the inverse theorem is an important basis for solving this part of the problem.The existence of the triangle, that is, both sides and greater than the third side, is the first condition of this part of the problem, a triangle has three corners, the three corners are likely to become a right angle, So doing
