论文部分内容阅读
中考题中出现了一系列填图、补图题,这类题融知识性、趣味性于一体,较好地考查了考生阅读、空间想象力、性质转化及应用能力,既易又活.要做好它们,应心中有图才行. 例1(2001福州)两个全等的三角板,可以拼出各种不同的图形.图1已画出其中一个三角形.请你分别补画出另一个与其全等的三角形,使每个图形分别成不同的轴对称图形(所画三角形可与原三角形有重叠部分).
In the examination questions, there appeared a series of graphs and supplementary drawings. These questions were combined with knowledge and interest. It was a good examination of candidates’ reading, spatial imagination, nature transformation, and application ability. It was both easy and lively. To do a good job of them, you should have a picture in mind. Example 1 (Fuzhou, 2001) Two equal triangles can be used to spell out a variety of different shapes. One of the triangles has been drawn in Figure 1. Please draw another one for the other. With its congruent triangles, each graphic has a different axisymmetric pattern (the drawn triangle can overlap with the original triangle).
