同学们,大家平时一定玩过镜子吧?其实,如果将平面镜反射光线的原理与学习平行线的知识结合起来,我们可以做出好多既有趣又实用的小玩具,是不是很感兴趣呢?那让我们一起来做吧.一、数学原理要做出这些小玩具,我们首先要了解平面镜反射光线的原理与平行线的相关知识,平行线的相关知识相信同学们已经掌握得很好了,平面镜反射光线的原理其实也很简单(如图1). Students, we usually have to play in the mirror, right? In fact, if the principle of flat mirror reflection of light with the knowledge of parallel lines to learn together, we can make a lot of both interesting and practical small toys, is not very interested in it? First, mathematical principles To make these small toys, we must first understand the principle of flat mirror reflection of light and parallel lines of knowledge, knowledge of parallel lines I believe the students have mastered very well, the plane mirror The principle of reflected light is actually very simple (Figure 1).
