摘要
根据画法几何综合问题所给定的条件,采用轨迹分析的方法,来确定问题是否有解,从而再确定它的解数,然后就可以根据分析出的轨迹采用适当的图解方法求出解答。
According to the condition which is assigned by descriptive geometry synthesis problems, we use the method that analyzes the path to determine whether the question does have the solution, thus determine its solution, then we may extract the explanation according to the path which is analyzed with the suitable graphic method.
