摘要
给出了三角形稳定性的本质含义、三角形稳定性的数学原理及其教学实施的策略,并用环形排列公式说明了四边形、五边形、六边形没有稳定性的数学依据.
This paper discusses the essential meaning and mathematical principle of triangle stability and its teaching strategies and recommendations.It is proved that quadrilateral,pentagon and hexagon have no stability by using the ring arrangement formula.
