平面向量作为高中数学重要的基本概念之一,它兼有代数与几何双重特性,是数形结合思想的有效载体.其中一些平面向量试题,其题面精巧、问题设置巧妙,且常常以向量的几何特征来呈现命制,该类试题其入口宽、解法灵活,可有效考查学生对平面向量基础知识与通性通法的掌握情况,能有效考查学生转化与化归的能力及其思维的发散性与敏捷性,具有较好的甄别功能. As one of the most important basic concepts in high school mathematics, Plane Vector is an effective carrier of the combination of numbers and shapes, because of its dual characteristics of algebra and geometry.For some of the plane vector test questions, Geometric characteristics to show the life of the test questions wide entrance, flexible solution can effectively examine the students basic knowledge of flat vector and general knowledge of the situation, can effectively examine the ability of students to convert and return and divergence of their thinking Sex and agility, with good screening capabilities.
