“线段垂直平分线性质定理”的内容是:线段垂直平分线上的点到线段两端的距离相等.这个定理体现了线段的轴对称性,运用该定理常可证明、构造有一个公共端点的两条线段相等.但在实际解题过程中,很多同学受思维定势的影响,常从全等的角度去证明两条线段相等,导致解题思路过于繁琐;或者对上述定理不熟悉,不能利用上述定理得到相等的线段去 “The theorem of the perpendicular bisector of the line segment ” is that the distance from the point bisecting the line perpendicular bisector to the two ends of the line segment is equal. This theorem reflects the axial symmetry of the line segment. Using this theorem can often prove that a common endpoint But in the actual process of solving problems, many students are influenced by their thinking tendency, often from the perspective of congruentness to prove that the two line segments are equal, leading to the problem-solving ideas too complicated; or not familiar with the above theorems, Can not use the above theorem to get the same line to go
