探索是一种重要的研究问题的方法,也是人们发现新知识的重要手段,非常有利于培养创新能力.探索问题包括从实践中探索、从特殊到一般的探索、存在性探索、动态探索等等,一般在各地中考都以压轴题形式出现.下面选取几个关联圆的综合探究型题,供同学们参考.一、类比探究型问题例1(2014年济宁市中考题)阅读材料:已知,如图1(1),在面积为S的△ABC中,BC=a,AC=b,AB=c,内切圆O的半径为r.连结OA、OB、OC,△ABC被划分为三个小三角形.
Exploration is an important method for researching problems and an important means for people to discover new knowledge, which is very conducive to cultivating innovative ability. Exploration includes exploration from practice, exploration from special to general, existential exploration, dynamic exploration and so on , Generally in the middle of the test are in the form of pressure axis questions below selected a few related to the round of comprehensive inquiry questions for students to reference. , As shown in Fig. 1 (1), BC = a, AC = b, AB = c and the radius of the inscribed circle O is r in △ ABC of area S. Link OA, OB, OC, △ ABC are divided into Three small triangles.
