摘要
推广了“勾股定理”及“余弦定理”,即 :如果直角三角形各边上的简单图形曲线相似 ,则其曲线弧长将仍能满足“勾股定理”,同时对于任意三角形“余弦定理”也成立 .这样 ,使定理的适用范围更加广泛 ,
In this paper, Gou Gu theorem and Cosine theorem are developed. Therefore, the scope of their application will be broaden. If simple curve graph of right angled trianggle rim is similar, then curve length will satisfy Gou Gu theorem, and general triangle will also conform to Cosine theorem.
