由于新课程改革对初中数学内容进行了一定程度的增删,中考中原来的一些考点、题型也发生了改变．随之而来是一些关于四边形和三角形的开放题、探索题成了中考压轴题的重要题型．这类问题不仅能考察知识,更重要的是能考查能力．下面以一些中考题为例,来谈一谈与四边形有关的探索题类型． Because the new curriculum reform has added or deleted the content of junior middle school mathematics to a certain extent, some of the original test sites and questions have also changed. Followed by some open questions about quadrilaterals and triangles, the exploration question has become an important question in the final exam.

The following uses some exam questions as an example to talk about the types of exploration questions related to quadrilaterals.
