几何问题中出现不等式称为几何不等式.这一类问题的证明或求解往往要或多或少地直接应用几何性质.几何最值是一类特殊的问题,它们强烈地体现着几何特性,而又灵活地综合了代数、三角等学科的知识.这是一类具有较高训练价值的综合题型.这类问题对培养分析问题和解决问题的能力极有帮助. The emergence of inequality in geometric problems is called geometric inequality. The proof or solution of this kind of problem often has to be more or less direct application of geometric properties. Geometrical value is a special kind of problem, they strongly reflect the geometric properties, and It integrates the knowledge of algebra, trigonometry and other disciplines flexibly.This is a type of comprehensive questions with higher training value.This kind of questions is very helpful for cultivating the ability of analyzing and solving problems.
