常见的图形运动有三种:轴对称、平移和旋转.这三种变换刻画了“两个全等图形”特定的位置关系,贯穿于三角形、四边形、圆等基本几何图形性质的研究.通过设置基于基本变换的试题,可以考查学生对基本图形本质的理解,又能考查学生的空间观念、动手操作、猜想验证 There are three common types of motions: Axisymmetric, translational, and rotational These three transformations characterize the “two congruent graphics” -specific positional relationships that span the basic geometric properties of triangles, quadrilaterals, circles, etc. By Set based on the basic transformation of the test questions, students can examine the nature of the basic graphics understanding, but also examine the students’ space concept, hands-on operation, guess validation
