在我们的周围有各种形状的物体,认识这些物体是学习几何知识的基本要求,于是人们把周围的物体分成几类,如柱体、锥体、台体、球体……平面图形也是如此,可分成三角形、四边形、多边形、圆……然后加以研究.研究什么呢?主要是研究图形的特点,便于我们应用于生活之中,研究的越深入越透彻,我们解决问题的方法和手段就越多.因此在研究几何图形时我们总要研究它的判别方法,它的性质……下面我们对一个与正方形有关的图形进行探索与研究,挖掘这个图形的内涵.
Around us are objects of all shapes and shapes. Understanding these objects is a basic requirement for studying geometric knowledge, so people classify the surrounding objects into categories such as cylinders, cones, tables, spheres, etc. The same is true of plane graphics, Can be divided into triangles, quadrilaterals, polygons, circles ... ... and then to study.What is the study? Mainly to study the characteristics of graphics, so that we can apply to life, the deeper the more thorough the study, our methods and means to solve the problem the more Therefore, when we study the geometry, we must always study its distinguishing method, its nature ... Next, we will explore and study a square-related graphics to explore the connotation of this figure.
