1.熟悉定理,活学活用“乱花渐欲迷人眼,浅草才能没马蹄。”很多学生对于几何证明题非常恐惧,看到纷繁多样的题目就茫然,觉得无从下手,关键是不熟悉几何中的常用性质与判定方法,更谈不上如何在各种题目中的灵活应用了。其实,万变不离其宗。在数学的证明题目中方法虽多,但并不是无章可循的。譬如证明边角相等一般脱离不了证明全等三角形这个框架,而以两角一边证全等方法最为常见,次之是边角边定理,只要 1. Familiar with the theorem, learn to use “Squatting for eye charming, Asakusa can not horseshoe. ” Many students for the geometric proof very scared, see a wide variety of topics at a loss, that no way to start, the key is not familiar Commonly used in geometry and judging methods, let alone how flexible in a variety of topics. In fact, ever-changing. There are many ways to prove the subject in mathematics, but it is not absent. For example, to prove that the same angle generally can not be separated from the proof triangle congruent framework, while the two sides of the card is the most common method of equivalence, followed by the edge of the theorem, as long as
