平移和旋转都是学生在日常生活中经常看到的现象。从数学的意义上讲,平移和旋转是两种基本的图形变换,平移和旋转对于帮助学生建立空间观念,掌握变换的数学思想方法有很大作用。
Panning and rotation are all things students often see in their daily lives. From a mathematical point of view, translation and rotation are two basic graphics transformations. Translation and rotation play a significant role in helping students to establish concepts of space and master mathematical transformations.
