中考中的几何、方程(equation)综合题,主要是指以线段长为根的一元二次方程问题.这类题将几何知识与一元二次方程有机结合,巧妙设计,既有几何的证明和计算,又有代数方程的变换和转化,综合考查几何、代数方程的基础知识和多方面能力.现以2002年典型试题为例,介绍这类题的命题特点和解题思路.
The comprehensive questions of geometry and equations in the entrance examination mainly refer to the one-dimensional quadratic equation with the root of the line segment as the root. This type of problem combines the geometric knowledge with the one-dimensional quadratic equation and is designed in an ingenious way. Calculations, in addition to algebraic equation transformation and transformation, comprehensive examination of the basic knowledge of geometric and algebraic equations and multi-faceted capabilities. Take the typical exam questions in 2002 as an example to introduce propositional features and problem-solving ideas.
