动态几何问题是以几何知识和几何图形为载体,渗透运动变化的一类问题,通过点、线、形的运动,图形的平移、旋转、翻折等把图形的有关性质和图形的数量关系、位置关系看做是变化的、相互依存的状态之中,要求对运动的变化过程伴随的数量关系、位置关系进行探究。能很好地考查学生学习数学的探究能力和综合素质,体现开放性,对学生分析问题的能力,对图形的想象能力,动态思维能力的培养和提高有积极的作用,受到老师和同学们的高度关注和 Dynamic geometric problem is based on geometric knowledge and geometry as a carrier, a kind of problem of infiltration movement change. Through the point, line, shape of the movement, the graphics of the translation, rotation, folding and so on the nature of the graphics and the relationship between the number of graphics, Position relationship as a changing, interdependent state, requiring changes in the process of movement accompanied by the number of relations, the relationship between location to explore. Can well examine students ’inquiry ability and overall quality of mathematics, embody openness, analyze students’ ability to analyze problems, have a positive effect on training and improvement of graphic imagination ability and dynamic thinking ability, Highly concerned and
