这是正在悄然兴起的一个中考热点,因为在直角坐标系中,几何图形的位置和大小都可以用“数”来表示,折叠问题又涉及全等变换和轴对称问题,下面通过2005年中考题来研究平面直角坐标系下的折叠问题.
This is a hot spot for examinations that is quietly rising. Because in Cartesian coordinates, the position and size of geometric figures can be represented by “numbers”. The folding problem also involves equal transformation and axisymmetric problems. The following questions were passed in 2005 To study the folding problem in a plane rectangular coordinate system.
