把一个图形分割成几块;将几个图形拼成另一个与之等积的图形;先把一个图形剪成几块,然后再拼成另一个与之等积的图形,这些都是图形剪拼问题.有趣的图形剪拼问题中常常蕴含着理性的数学思考,要求解题者进行多方位、多角度、多层次探索,可以培养解题者思维的灵活性、发散性和创新性.笔者例析几例,与同仁共赏.1图形的分割(裁剪)
Divide a graph into several pieces; Combine a few figures into another equal-integral figure; First cut a figure into several pieces, and then spell it into another equal-integral figure, which are both graphic cut Spelling problems.Important graphic clipping spell problems often contain rational mathematical thinking, requiring solvers to multi-directional, multi-angle, multi-level exploration, you can cultivate the flexibility of the problem-solving thinking, divergence and innovation.
