在初中数学的学习中,转化思想应用极为广泛,无论是平面几何证明问题、不等式问题或是方程问题,都离不开转化思想的运用.通过转化,可以将复杂的问题简单化、抽象的问题具体化,在提高解题效率的同时还能锻炼同学们的数学思维,提高解答问题的能力.一、添加辅助,无中“生”有在全等三角形的证明题中,离不开辅助线的添加.添加辅助线之后,可以将原本并不存在的全等三角形构造出来,利用已知的条件,转化为新的等量关系,从而做到“无中生
In the study of junior high school mathematics, the idea of transformation is extremely extensive, and it is inseparable from the application of transformation thought whether it is plane geometry proof, inequality problem or equation problem. Through the transformation, the complex problem can be simplified and the abstract problem Specific, in improving the efficiency of problem solving, but also exercise students’ mathematical thinking, improve the ability to answer questions .A supplemental auxiliary, without ”“ Health ”in the proof of congruent triangle, can not be separated After adding the auxiliary line, you can construct the congruent triangle that does not exist and make use of the known conditions to convert it into a new equivalent relationship so as to achieve "
