轴对称是数学研究的重要内容,也是解数学题的一个重要工具。证明某些较为复杂的几何题时,往往要通过添辅助线才能解决。添辅助线的主要方法是将某些图形的位置进行适当的变换,使已知条件和要证明的结论建立起明显的关系,以便运用定理、公理,通过逻辑推理去解决。在证题过程中,? Axisymmetrical is an important part of mathematics research and an important tool for solving mathematics problems. To prove that some of the more complex geometric problems are often solved by adding auxiliary lines. The main method of adding auxiliary lines is to transform the positions of certain graphics appropriately so that the known conditions and the conclusions to be proved establish a clear relationship so that theorem and axioms can be used to solve them through logical reasoning. In the process of certification,?
