随着时代的发展,作图工具越来越精细、多样,至今我们仍强调尺规作图,其主要原因是:一、几何研究的对象不外是直线、圆以及其组合图形,用圆规和直尺,已能精确地作出令人神往的图形;二、尺规作图不仅工具最简单,使用方法也最简便,只限于用尺规作出符合一定条件的几何图形,无疑具
With the development of the times, drawing tools are getting more and more elaborate and diverse. So far we still emphasize the rule-making. The main reasons are as follows: First, the objects of the geometric research are nothing more than straight lines, circles and their combinations, Ruler, has been able to make a fascinating figure accurately; Second, the rules and regulations not only the simplest tools for the most simple and easy to use, only to use rules to make certain conditions consistent with the geometry, no doubt
