数形结合作为一种重要的数学思想,历年来一直是中考考查的重点之一.这种思想体现在解题中,就是指在处理数学问题时,能够将抽象的数学语言与直观的几何图象有机结合起来思索,促使抽象思维和形象思维的和谐复合,通过对规范图形或示意图形的观察分析,化抽象为直观,化直观为精确,从而使问题得到简捷解决. As an important mathematical thought, the combination of number and shape has been one of the key points in the middle school examinations over the years.This kind of thinking is reflected in the problem solving, which means that when dealing with mathematical problems, it can combine abstract mathematical language with intuitive geometric figure As the organic combination of thinking, and promote the abstract thinking and image of the harmonious combination of thinking, through the specification of graphics or schematic observation and analysis, abstract abstraction is intuitive, intuitive and accurate, so that the problem can be solved simply.
