抛物线与几何图形的有机结合,可以构建综合题和探究型试题,特别是有关抛物线中三角形面积的最值问题,更是各地中考考查的热点题型。多数学生遇到这种综合题通常不知如何入手。因此,精选一道既能解决问题又能提升能力的好题对学生进行解法指导显得尤为重要。本文以一道中考题为例,对抛物线中三角形的面积最值问题进行解法探究。
Parabolic and geometric combination of organic, you can build comprehensive questions and research questions, especially on the triangle area of the parabola, the most valuable problem, but also around the exam in the hottest questions. Most students often do not know how to start this comprehensive question. Therefore, the selection of a good problem that can both solve the problem and improve the ability of the students to guide the solution is particularly important. In this paper, taking a middle school entrance exam as an example, this paper explores the most important problem of the area of the triangle in the parabola.
