实施素质教育应以培养学生的创新精神和实践能力为重点,今就矩形的折叠谈谈数学教学如何体现这一观念.一、对折已知矩形纸片ABCD,AB>AD(图1).1.若沿着AB对折(图1),所得矩形AEFD能否与原矩形ABCD相似?若相似,AB∶AD的值是多少?简解:可
The implementation of quality education should focus on cultivating students’ innovative spirit and practical ability. Now we talk about how the teaching of mathematics embodies this idea about rectangular folding. 1. Fold the known rectangular paper ABCD, AB>AD (Figure 1). 1. If you fold along AB (Figure 1), can the resulting rectangular AEFD be similar to the original rectangle ABCD? If similar, what is the value of AB:AD? Simple Explanation:可
