三角形的“四心”(即内心,外心,重心,垂心)是中学数学的一个基础知识点,需掌握它们的定义和性质.近几年,以平面向量知识为载体,加强了对它的考查,是高考的一个小的热点.本文就“四心”判断问题的解题方法作一归纳,供读者参考. The triangle’s “four hearts” (ie, inner heart, outer heart, center of gravity, and vertical heart) are a basic knowledge point for middle school mathematics. It is necessary to grasp their definition and nature. In recent years, the use of plane vector knowledge as a carrier has strengthened the Its examination is a small hot spot of the college entrance examination. This article summarizes the problem solving method of the “four hearts” judgment problem for readers’ reference.
