The difference between translation and rotation is that in graphics, a graphic changes from one place to another, and this process is called translation. A figure rotates to a certain angle around a fixed point, and this process is called rotation.

In the process of accurate translation, no matter which corresponding point, their forward directions remain parallel. The most important point of rotation is that in the process of precise rotation, rotation is only a circular motion around a point or axis. Whether it is rotation or translation, the process of both will not cause the state and size of the graph to change, and the distance between corresponding points will remain unchanged.

"Translation and rotation" are two abstract concepts, but translation and rotation are everywhere in life. Mathematically speaking, translation and rotation are two basic graphic transformations. The translation and rotation of graphics play a great role in helping students to establish the concept of space and master the mathematical thinking method of reduction. Therefore, in teaching, we should fully consider students' cognitive level, find the connection between new knowledge and students' existing experience, select as many familiar and interesting life cases as possible, and at the same time pay attention to highlighting the essential attributes of the selected cases, so that students can grasp the characteristics and achieve the initial perception effect. This lesson is mainly for students to operate fully and observe carefully, so that students can experience the knowledge of "translation and rotation" in "learning by doing", thus cultivating students' practical ability and innovative consciousness, enabling students to obtain good emotional experience and improve their learning ability.
