由于几何题的证明千变万化，错综复杂，不象代数那样有法则或公式可套用，因而使初学几何证明的同学颇感困难．那么，怎样进行几何证明呢？经验告诉我们，首先要做好证题前的准备工作：（１）仔细阅读题目，深刻理解题意，分清题中哪一部分是已知，哪一部分是结论，并画出合乎? Because the proofs of geometric problems are ever-changing, intricate and complex, unlike algebra, there are laws or formulas that can be applied, making it difficult for beginners to prove their classmates. So, how do you prove the geometry? Experience tells us that we must first do a good job of preparation before the test: (1) Read the questions carefully, deeply understand the meaning of the questions, distinguish which part of the questions are known, which part is the conclusion, and draw a conclusion.
