以具体问题为例,对立体几何中求线段之和最小值问题进行了分析研究,意在加深学生对该类问题的理解掌握,以期提高学生发挥空间想象力,把空间问题转化为平面问题来解决的能力.
Taking the concrete problems as an example, this paper analyzes and studies the minimum sum of the line segments in the three-dimensional geometry, which aims to deepen the students ’understanding and mastery of these kinds of problems so as to improve the students’ imagination in space and turn the space problem into the plane problem Ability to solve.
