从几何问题中确定一次函数解析式,是把几何问题与一次函数知识巧妙结合的一种题型,它将代数、几何知识融为一体.此类问题的特点是应用知识广泛,结构新颖,解法无固定模式可循,通常通过“形”与“数”之间的对应、转化来解决问题.因此,这类问题比一般综合题更能考查综合运用数学知识的能力,并且成为中考中常考不衰的热点问题之一.
Determining the analytical function of a function from a geometric problem is an ingenious combination of geometric problems and knowledge of one-way function. It combines the knowledge of algebra and geometry. The characteristics of such problems are wide application knowledge, novel structure, and solutions. There is no fixed pattern to follow, usually through the correspondence and transformation between “shape” and “number”. Therefore, this type of problem can examine the ability to use mathematical knowledge comprehensively and more often than the general comprehensive question, and become a frequent test in the middle of the exam. One of the hot issues.
