解数学题时,我们有时觉得容易,可是过后又发现有这样那样的不该出现的错误,并且这种现象还屡见不鲜.古人云:前车之辙,后车之鉴.正视错误,分析产生错误的原因,防患于未然,是增强解题效果所必需的,也是巩固“双基”的一种必要措施.为此,本文就四边形中常见的一些错误解法进行归类分析,剖析其产 When solving mathematics problems, we sometimes find it easy, but later found that there should be such errors should not appear, and this phenomenon is still commonplace. The ancient saying goes: the front of the car, learn from the past. Face errors, analysis error The reason why preventing problems before they occur is necessary to enhance the effect of solving problems, and it is also a necessary measure to consolidate the “dual basis.” Therefore, this article classifies and analyzes some common error solutions in the quadrilateral and analyzes them.
