6 . 数学探究:用向量法研究三角形的性质.向量集数与形于一身,每一种向量运算都有相应的几何意义.向量运算与几何图形性质的内在联系,使我们自然想到:利用向量运算研究几何图形的性质,是否会更加方便、便捷呢?在数学研究中,常常用新的工具、新的方法对已研究过的对象进行再研究,这不仅可以站在新的高度审视研究对象,而且还可以有所发现.三角形是几何中最简单的封闭图形,但它是最重要的基本几何图形之一.三角形的性质非常丰富,是联系各种几何图形的纽带.在平面几何中,我们已经研究过三角形的一些基本性质,但对三角形的认识还不够深入,例如对三角形的外心、中线、重心、角平分线、内心、高、垂心等只有初步认识.因此,以向量为工具对三角形进行再研究是非常有意义的.
