海伦三角形与海伦数组

Heron Triangle and Heron Array

边长a,b,c及面积都为整数的三角形称为海伦三角形,(a,b,c)称为海伦数组,勾股弦数组即是海伦数组。海伦数组和海伦三角形是大量存在的,文章提出了一种由勾股弦数组构造海伦数组的方法。

Triangle of integer side lengths is called Heron triangle. Suppose the three side lengths are a, b and c, then （a, b, c） is called Heron array. Pythagorean array is namely Heron array. Generally, one Pythagorean array can generate two Heron arrays, and two Pythagorean arrays can generate 8 Heron arrays.
