《几何原本》是欧几里得1最重要的数学著作,它是对古希腊数学的一次总结,全书共有13卷(有些书中认为是15卷).第1、2、3、4、6、11、12、13卷的内容属于几何学,剩下的5卷属于现今的算术和数论,全书共有命题636个.在一次数学史的课上,老师讲到《几何原本》第一卷和第二卷中的一些命题,课后我对这些命题进行整理,发现有些命题稍加变形就是我们现在教材中的一些定理或公式,但在古希腊时期, The Geometry Original is the most important mathematical work of Euclid 1, a summary of ancient Greek mathematics, with a total of 13 volumes (15 in some books). , 11,12,13 volumes belong to geometry, the remaining five volumes belong to today’s arithmetic and number theory, the book total of the proposition 636. In a history of mathematics, the teacher talked about “Geometry” the first volume and Some of the propositions in the second volume, after class I organize these propositions and found that some of the proposition a little deformation is some of the theorems or formulas in our teaching materials, but in ancient Greece,
