立体几何问题中蕴涵着丰富的数学思想方法,其中应用最多的就是等价转化的思想,它是求解立体几何题的思维主线下面通过举例,简析几种解答题的转化策略,供参考.一、异面直线所成角中的转化异面直线是空间概念,异面直线所成的角是利用平移变换把空间角转化为平面上角的问题,常用的转化手段是通过中点
Three-dimensional geometric problems contain a wealth of mathematical thinking methods, of which the most widely used is the idea of equivalent transformation, which is the main line of thinking to solve the problem of three-dimensional geometric problems through examples below, analysis of several answer questions conversion strategy for reference. , The angle of heterogeneous straight line into the corner of the transformation is a non-linear concept of space, the angle formed by the different surface straight line is the use of translational transformation of the spatial angle into a corner on the plane, the common means of conversion is through the midpoint
