近几年中考压轴题以动态型函数与几何的综合题居多,此类题型灵活多变,往往难以想像其变化后的图形,我们对这类题型的解法要善于总结,笔者对近年压轴题中较多的蕴含“特殊直角三角形”题型进行了分析,发现常见有以下几种特殊直角三角形. In recent years, most of the comprehensive questions in dynamic subjects and geometry have been studied in recent years. These types of questions are flexible and often difficult to visualize their changed figures. Our solutions to such questions should be good at summing up. There are more “special right-angled triangle” questions in the analysis. It is found that there are several special right-angled triangles.
