动态问题是以点、线段、角、三角形、特殊四边形或其他图形作为基本条件,借助于几何图形的变化:如点、线的移动,三角形形状的变化,图形的平移、翻折、旋转,图形的相似(位似)等,研究不同图形变换的特殊性质,以及通过图形的变换构造新的图形与数量关系。给出一个或更多个变化的量,并要求能够确定变量与其他量之间的关系,同时注意利用其他数学知识,进行相关的几何计算或数形结合的数学思想的变化应用,从而将问题顺利解答。
Dynamic issues are based on points, line segments, corners, triangles, special quadrilaterals, or other graphics as a basic condition, with the aid of geometric changes such as point and line movements, changes in the shape of triangles, translation, folding, turning, Similarity (bit like), etc., to study the special nature of different graphics transform, and through the transformation of graphics to construct a new relationship between graphics and quantity. Given one or more variable quantities, and requiring the ability to determine the relationship between variables and other quantities, noting the use of other mathematical knowledge to make relevant mathematical calculations or mathematical applications of mathematical combination, Smooth answer.
