数学学习中,很多同学往往喜欢做大量的课外习题,而对于数学书常常丢在一旁,很少花时间去研读,这种做法是有失偏颇的,殊不知教材中的例题习题具有很强的代表性,如果我们能多花时间去仔细研究,多做一些思考,必定会有收获.下面我就为大家介绍一个由苏科版教材复习题所引发的思考.教材中的原题(苏科版八下P123复习题探索研究15题):如图1,有两个分别涂有黄色和蓝色的△ABC和△A′B′C′,其中∠C=∠C′=90°,且两个三角形不相似.问:能否分别用一条直线
In mathematics learning, many students often like to do a lot of extracurricular exercises, but often forget about math books and spend less time studying. This practice is biased, and it is not known that the examples in the textbooks have a strong representation Sex, if we can spend more time to study carefully, do more thinking, there will be a harvest. Now I will introduce for you a reflection of Su Ke version of the textbook review questions triggered by the original textbook (Su Keban Eight P123 review questions to explore the study 15 questions): Figure 1, there are two were painted with yellow and blue △ ABC and △ A’B’C ’, where ∠C = ∠C’ = 90 °, and two A triangle is not similar. Q: Can use a straight line
