探究:如图13.1-6,直线l垂直平分线段AB,P_1,P_2,P_3……是l上的点,分别量一量点P_1、P_2、P_3……到点A与点B的距离,你有什么发现?可以发现,点P_1、P_2、P_3……到点A的距离与它们到点B的距离分别相等……由此,我们可以得出线段的垂直平分线性质:线段垂直平分线上的点与这条线段两个端点的距离相等——(A)(人教版初中数学八年级上册61页)命题(A)并没有正确 Explore: As shown in Figure 13.1-6, the straight line l perpendicular bisector AB, P_1, P_2, P_3 ... is the point on the l, the amount of a small amount of points P_1, P_2, P_3 ...... to the point A and B distance, you What can be found? It can be seen that the distances from points P_1, P_2, P_3 ... to point A are equal to their distances from point B, respectively ... Thus, we can get the vertical bisector of the line: (A) (PEP Middle School Math Grade 8, Volume 61) proposition (A) is not correct
