中考试题中常常有一些没有给出图形的几何试题,存在着多解的可能.解答此类问题时,常因概念不清、思维定式、忽视分类、考虑不周等,造成构图失误,从而导致漏解的发生.下面举例说明,希望能够对同学们有所警示.一、因概念不清造成漏解正确地理解和运用概念是学好数学的基础,概念不清就容易陷入思维混乱,导致判断、推理或理解错误. There are often some geometric questions in the test questions are not given the graphics, there is the possibility of multiple solutions to answer such problems, often due to unclear concepts, thinking style, ignoring the classification, consider the ill-considered, resulting in composition errors, resulting in The following example, hoping to be able to give some warnings to students.First, due to unclear concepts caused by misunderstandings Correct understanding and use of the concept is to learn mathematics, the concept of confusion is easy to fall into chaos, leading to judge , Reasoning or understanding mistakes.
