线段的垂直平分线(也称中垂线),是平面几何中的一个重要内容,备受中考命题者青睐.在中考中,相关考查以基础知识、基本技能为主,对尺规作图的考查有所加强,侧重于性质定理和逆定理的运用.题型方面,多为中低难度的选择题、填空题,也有中等难度的解答题,常与等腰三角形、直角三角形的相关知识融合,有一定的综合性.一考查概念理解 Vertical bisector of the line segment (also known as the vertical line), is an important aspect of plane geometry, much favored by the senior high school entrance examination in the test, the relevant test to basic knowledge, basic skills, the rules of the rules Tests have been strengthened, focusing on the use of the nature of the theorem and the inverse theorem .Types, mostly low to medium multiple choice questions, fill in the blank questions, there are moderate difficulty answer questions, often associated with isosceles triangle, right triangle fusion of knowledge , There is a certain degree of comprehensiveness
