一般来说,一个较复杂的几何图形中往往蕴含着若干个基本图形,善于从复杂的几何图形中提取和利用基本图形常常是解决问题的关键.不仅如此,有了大量的基本图形及其特性的积累,还可以大幅度提高思考问题的速度.本文介绍一个有着广泛应用的基本图形.
In general, a more complex geometry often contains a number of basic graphics. Being good at extracting and using basic graphics from complex geometries is often the key to solving problems. Not only that, there are a large number of basic graphics and their features. Accumulation can also greatly improve the speed of thinking about the problem. This article describes a basic graph with a wide range of applications.
