平面向量运算体系是继实数运算体系之后的第二运算体系,有其完善的概念、计算公式、共线共面定理、几何运算法则、代数运算法则、运算律、性质,它是解决物理矢量问题和数学几何问题的有力工具,它能把平面几何的全等、相似、平行、垂直、夹角、距离转化成平面向量的线性运算、数量积运算,而把研究平面图形的几何性质转化成平面向量的运算(空间向量与立体几何关系也如此)。正因如此,平面向量是高考命题的重点。下面对今年的高考题分类导析。
Plane-vector computing system is the second computing system following the real-number computing system, with its perfect concept, calculation formula, collinear coplanar theorem, geometric arithmetic, algebraic arithmetic, arithmetic law, property, which is to solve the problem of physical vector It can convert the geometrical congruence, similarity, parallelism, verticality, included angle and distance of planar geometries into linear arithmetic and numerical product arithmetic of plane vectors, and transform the geometrical properties of studying planar geometries into plane The vector operations (spatial vector and the geometric relationship as well). Because of this, the plane vector is the focus of college entrance examination proposition. The following classification of the entrance exam this year.
