用轴对称设计图案主要考查学生的空间想像能力和设计、实践能力,问题一般具有较强的应用性和开放性.正确应用轴对称的性质是设计图案的关键.图1例1某街道办事处欲建造一居民文化公园,将12个场馆排成6行,每行4个场馆,办事处将如图1所示的设计图案公布后,引起一群初中生的好奇,他 The use of axisymmetric design patterns mainly examines students’ spatial imagination ability and design and practical abilities. The problems are generally of strong applicability and openness. The correct application of axisymmetric properties is the key to the design pattern. Figure 1 Example 1 Street office To build a residential cultural park, 12 venues will be arranged in 6 rows with 4 venues per row. The office will publish the design pattern shown in Figure 1 and cause a group of junior high school students to be curious.
