在学习几何的过程中,图形是我们经常见到的基本元素,可以说,没有图形就不谈几何,几何图形是这样定义的:“点、线、面、体这些可帮助人们有效地刻画错综复杂的世界,它们都称为几何图形”。众所周知,点动成线,线动成面,面动成体,在不停的图形运动中,产生出不 In the process of learning geometry, graphics are the basic elements that we often see. It can be said that no geometry is not involved without geometry. Geometry is defined as follows: “Points, lines, faces and bodies can help people to effectively describe Intricate world, they are called geometry ”. As we all know, point into a line, moving into a surface, the surface moving into the body, in the non-stop graphic movement, produced no
