现在的数学越来越注重对探究能力.创新意识的培养.相应地,题型正逐步由过去的封闭型转向为探索型.图形之间的位置关系是几何题中的重要条件,且位置关系是可变的,这样通过变化位置关系,使结论具有探索性的问题也就成为考题的热点,下面就此问题读一些常见类型. Today’s mathematics is increasingly focusing on cultivating the ability to explore and innovate. Correspondingly, the questions are gradually shifting from the closed type to the exploratory type. The positional relationship between graphs is an important condition in the geometrical problem, and the positional relationship Is variable, so that by changing the location of the relationship, so that the problem of exploratory conclusions has become a hot topic of the examination, the following read some common types of this issue.
