轴对称是数学中应用最广泛的一种初等变换,在解(证)题的过程中,如果已知的图形中有轴对称或者根据题设和具体图形构造出轴对称图形,那么可以充分利用轴对称的性质,直接得出有关三角形全等,从而使问题快速得到解决,也使解题过程更加简捷,下面通过实例谈谈其在解题中的应用. Axicon symmetry is the most widely used primary transformation in mathematics. In the course of solving problems, if the known graph has axial symmetry or the axisymmetrical map is constructed according to the questions and the specific graph, then it can be fully utilized. The nature of axisymmetric, directly drawn on the congruence of the triangle, so that the problem is quickly resolved, but also to make the problem-solving process more simple, the following example to talk about its application in solving problems.
