河北区九年级二模数学试题视频讲解,附试卷下载方式

       二模都考完了，试卷还在整理，下载试卷可以明天再来看看。

       今天先讲题。

       河北区九年级二模第17题

      看着很简单，其实一点都不简单的一道题。用模型可以很快得到算式，但是根号下套根号，真的能算出来吗？考场上时间允许吗？来看看我的这个方法吧

       河北区九年级二模第18题

       就是过任意点作平行，好像并不难。而因为AM是格线，所以这个题应该能有比较省事的方法。还是得嘱咐，如果数学没有稳定在117+，不要在这道题上耽误太多时间。

       河北区九年级二模第24题

       稍微有一点创新的平移+翻折，图里的矩形是歪着的。而因为边长已知，可以根据锐角三角函数来快速确定线段之间的关系，计算量不是很大，同时还需要一些解题技巧。

      今年的模考25题，属这道题计算量小，需要思考的点少。个人感觉只要有时间，这个题就能做。

       和其他题一样的地方，就是都得自己动手画图
