1平面向量在高中数学中的地位和作用平面向量是高中数学的必修内容,也是近年来高考命题的热点之一,它架起了代数、三角函数、几何等知识沟通的桥梁。在向量这个概念引入之后,几何中涉及的全等、平行、相似、垂直、勾股定理等就可以转化为向量的加(减)法、数乘向量、数量积运算,从而把图形的基本性质转化为向量的运算体系。这些对自 Plane Vector Placement and Function in High School Mathematics Plane vector is a compulsory part of high school mathematics. It is also one of the hot topics of college entrance examination in recent years. It sets up a bridge of knowledge communication such as algebra, trigonometry and geometry. After the concept of vector is introduced, the congruence, parallelism, similarity, verticality, and Pythagorean theorem involved in geometry can be transformed into vector addition, subtraction, number multiplication and number product operations, so that the basic properties of graphics Conversion into a vector of computing systems. These are right
