将矩形按不同要求进行折叠,就会产生丰富多彩的几何问题,而这些问题中往往融入了丰富的对称思想,综合了三角形、四边形的诸多知识,千变万化,趣味性强,考查了学生的探究能力、空间想象能力、抽象思维能力及逻辑推理能力。因此越来越受到各省中考命题者的青睐。在解决这类问题中,运用的知识点比较多,综合性强,如轴对称性、全等思想、相似思想、勾股定理等,是培养学生识图能力,灵活运用数学知识解决问题能力的一条非常
Rectangles will be folded according to different requirements, it will produce a variety of geometric problems, and these problems are often integrated into a wealth of symmetry ideas, a combination of triangles, quadrilateral knowledge, ever-changing, interesting, examines the students’ ability to explore , Spatial imagination ability, abstract thinking ability and logical reasoning ability. Therefore, more and more by the provincial senior high school entrance examination candidates of all ages. In solving such problems, the use of more knowledge points, comprehensive strong, such as axis symmetry, equal thought, similar thinking, the Pythagorean theorem, is to develop students ability to identify the image, the ability to use mathematical knowledge to solve problems A very
