三角形内切圆的计算机求解

The Programming Solution of Inscribed Circle of Triangle

数学上求三角形内切圆传统的方法是求出三角形两个角的角平分线交点作内切圆的圆心,然后再求出内切圆的半径。但这种方法用计算机程序实现时要考虑的情况很多,实现复杂。文章就此提出改进办法,简化计算机程序实现。算法采用Visual C++描述。

The traditional mathematical method to acquire the inscribed circle of a triangle is to fix the intersecting point of two angular bisectors as the center of the inscribed circle. Yet when it is to be realized by computer program, many situations have to be brought into consideration, which makes it difficult to realize. This paper suggests an alternative that might improve the method and simplify the computer programming. It is described in terms o.f Visual C＋＋.
