在江苏省对口单招数学试卷中,立体几何这一章的知识点每年都作为重点考查的内容.每年我校考生在立体几何解答题上的得分情况都不太理想.向量是基本的数学概念之一,是沟通代数与几何的工具之一,体现了数形结合的思想.根据向量的数形特性,可以将几何图形数量化,从而通过运算解决立体几何中的平行、垂直等问题,能避免构图和推理的复杂过程,有利于降低解题难度.
In the Jiangsu province counterparts single mathematics papers, three-dimensional geometry of the knowledge points in each chapter as a key examination of the contents of each year my school candidates in the three-dimensional geometry problem scores are not ideal.Vector is the basic mathematical concepts One of them is one of the tools to communicate algebra and geometry, which embodies the idea of combination of number and shape.According to the number-shape characteristics of vectors, we can quantify the number of geometric figures to solve the problems of parallelism and verticality in solid geometry through calculation Avoid the complex process of composition and reasoning, help to reduce the difficulty of solving problems.
