三角形中的“四心”深刻的刻画了三角形的性质,在研究三角形中起着举足轻重的作用。在高中教学内容中,三角函数及解三角形、向量、立体几何、解析几何等章节都需要用上三角形“四心”的知识。笔者试着结合多年的教学经验在这类问题谈谈自己的心得。 The “four hearts” in the triangle profoundly depict the nature of the triangle and play a decisive role in the research triangle. In high school teaching content, trigonometric functions and triangular, vector, solid geometry, analytic geometry and other chapters need to use the triangle “four hearts ” knowledge. I try to combine years of teaching experience in such issues to talk about their own experiences.
