数形结合是高中数学重要的思想方法。代数关系和几何关系之间的相互转换，往往能够使问题更加形象和直观。然而一些复杂的代数关系很难通过人工画图快速、准确地反映出来，而且人工画图难以体现变量变化、几何对象的动态变化时，我们需要借助动态数学软件。而动态数学软件 GeoGebra 拥有强大的作图功能，可以方便快捷地搭建起把“数”与“形”结合在一起的桥梁，实现代数问题的可视化。

Symbolic-graphic combination is an important think-ing method in mathematics for senior high school. The intercon-version between algebraic relations and geometrical relations can often make problems more visual and intuitive. However, some complicated algebraic relations can hardly be rapidly and accu-rately reflected through artificial drawings which can hardly re-flect the dynamic changes of geometric objects with the changes of variables, so we should draw support from dynamic mathemat-ical software in this case. The dynamic mathematical software GeoGebra possesses powerful functions of drawing, which can rapidly make algebraic problems visualized through symbol-ic-graphic combination.
