向量是作为一种数学工具引进新教材的, 而三角形与向量的结合可谓是“珠联璧合”.这类问题在高考和各种模拟考试中频频亮相,成为一道亮丽的风景. 一、与向量结合的三角形的“五心”问题三角形的“五心”:内心、外心、垂心、重心、傍心,在向量包装下让人耳目一新. Vectors are used as a mathematical tool to introduce new textbooks, and the combination of triangles and vectors can be described as a “joint match.” Such questions frequently appear in college entrance examinations and various mock exams to become a beautiful landscape. First, combined with vectors Triangle’s “Five Hearts” Problem Triangle’s “Five Hearts”: inner heart, outer heart, vertical heart, center of gravity, and heart-wrench are refreshing in vector packaging.
