矩形折叠问题在初中数学学习中屡见不鲜,解答它们必须明白,折叠实质上是一种对称变换,折痕是其对称轴,折叠后能够完全重合的部分是全等图形,它们的对应角相等、对应线段相等.现以中考题为例介绍如下: Rectangular folding problems are common in junior high school mathematics learning. To answer them, we must understand that the folding is essentially a symmetric transformation. The crease is its symmetry axis. The part that can be completely overlapped after folding is the congruent graph. Their corresponding angles are equal and correspond to each other Line segments are equal. Now take the test questions as an example is as follows:
