一、点的对称问题的解法 1.点与点关于点成中心对称的解法: 根据中心对称的定义,点与点关于点成中心对称时,对称中心即为两对称点的中点。这类问题可由中心坐标公式解决。 〔例1〕求点M(a,b)关于点A(0.1)的对称点 解:设点M(a,b)关于点A(0,1)的对称点为M First, the point of the symmetry problem solution 1. Points and points on the point into the center of symmetry solution: According to the definition of central symmetry, point and point on the point when the center symmetry, the symmetry center is the middle point of the two symmetrical points. Such problems can be solved by the central coordinate formula. [Example 1] Find the symmetry point of point M(a,b) with respect to point A(0.1) Solution: Set point M(a,b) as the point of symmetry of point A(0,1) to M
