一、要熟练掌握几何基础知识。首先要认真研读书本内容,正确理解几何概念、定理、公理、公式等。其次掌握识图、作图等技能;充分发挥例题、习题的作用,模仿例题的解法和思路;决不放过习题的训练机会,不断归纳总结。这既是学好证明的基础又是证明的依据,只有熟练掌握它们,才能进行几何证明。 First, master the basic knowledge of geometry. First of all, we must carefully study the contents of this book, and correctly understand the geometric concepts, theorems, axioms, formulas, and so on. Second, master the skill of graphing and graphing; take full advantage of the examples and exercises; imitate the solutions and ideas of the examples; never give up the training opportunities for the exercises and continue to summarize. This is both the basis for proof and the basis for proof. Only by mastering them can we prove the geometry.
