解三角形最值模型
Solving the Triangle-Maximum Model

解三角形是高中数学的重要内容，其中三角形周长与面积的最值是高考考查的一个热点问题，本文以三个不同类型的例题为载体，通过层层深入分析，从几何与代数不同角度总结出解决三角形周长与面积最值问题的方法和策略，扩宽解题思路，以期对学生提供一些参考与借鉴。
Solving triangles is an important content of high school mathematics, and the maximum value of the perimeter and area of a triangle is a hot topic in the college entrance examination. This paper takes three different types of example problems as the carrier, and summarizes the methods and strategies to solve the problem of the most value of the perimeter and area of a triangle from different perspectives of geometry and algebra through in-depth analysis, so as to broaden the ideas of solving the problem and provide some reference and reference for students.
