文[1]中将三边长a,b,c是互质的自然数,且恰有一内角为60°或120°的三角形定义为锦云三角形,记为(a,b,c),并给出了通过含120°角的锦云三角形得到含60°角的锦云三角形的方法,罗列了锦云三角形的几个模型,提出了有待解决的几个问题.笔者通过对含120°的锦云三角形的模型的进一步研究,提出几点补充看法,建立一个简洁的模型,以供原文作者和读者参考.文[1]列出的含120°的锦云三角形模型为 In [1], the length a, b, c of the three sides are the natural numbers of the coprime, and the triangle which exactly has an inner angle of 60 ° or 120 ° is defined as the golden cloud triangle, denoted as (a, b, c) The method of getting the triangle of the cloud and the cloud containing the angle of 60 ° through the triangle of the cloud and the angle of 120 ° is given and several models of the triangle of the triangle and the triangle of the cloud are listed and some problems to be solved are put forward. Further study of the model of cloud triangles, put forward some additional ideas, to establish a concise model for reference by the original author and reader.
