一、学习目标1、理解两个图形关于一条直线成轴对称的意义2、掌握“轴对称图形”与“两个图形关于一条直线成轴对称图形”的区别与联系3、通过实践操作,探究成轴对称的两个图形的性质4、应用性质画已知图形关于某一条直线对称的图形5、能画出成轴对称的两个图形的对称轴【设计依据】轴对称与我们的现实生活联系紧密,它不但与图形的三种运动方式平移、旋转、翻折有着不可分割的联系,为今后研究等腰三角
First, the learning objectives 1, to understand the meaning of the two graphics on a straight line into an axisymmetric 2, to grasp the “axisymmetric graphics” and “two graphics on a straight line into an axisymmetric graphics ” the difference and contact 3, through Practice the operation to explore the nature of the two graphics axisymmetric 4, the nature of the application of the known graphics on a straight line symmetrical graphics 5, can be drawn as two axes symmetric axisymmetric design 【Design】 Axisymmetric and Our real life is closely linked. It not only has an inextricable connection with the three modes of movement of the graphic, such as translation, rotation and turning over, but also studies the isosceles triangle
