摘要
讲述了用运动、动态的观点来解初中平面几何题,它可以将一个图形沿着某一点旋转一个角度以后,使较复杂的问题简单化,体现了一种几何变换的数学思想,从而达到简捷明快的解题目的。
Dynamic view in solving problems in plane geometry can make complex more simple by rotating a graphics fixed on a certain point to a certain angle. This method embodies a rans-positional teaching concept, so it becomes more efficient in solving geometrical problems.
