What is a translation of an image?The translation of an image is that in a plane, a graph moves from one position to another in a certain direction without changing its shape or size.The characteristics of image translation are: 1, the image from a position to another position, the size of the image does not change;2. The shape of the image does not change after moving from one position to another;3. After the image is moved from one position to another, any point on the graph moves the same distance;4. After the image is moved from one position to another, any point on the image moves in the same direction, and the connecting line segments between the two points will be parallel to each other.5. After the image translation, the corresponding line lengths will be equal, and the corresponding angles will also be equal.So a translation of an image is a straight line movement of the whole image.What is rotation of an image?Image rotation refers to a graph in the same plane around a point or a line in a clockwise or counterclockwise circular motion.The characteristics of image rotation are as follows: 1. The size and shape of the image are not changed in the process of image rotation;2. During the rotation of the image, each point on the image is centered on the same point and moves in the same direction.3. The trajectory of each point on the image is an arc, and the distance is not equal;4. The included Angle of movement of each point on the image is equal;5. After the image is rotated, the corresponding line segment and corresponding Angle are equal.The link between image translation and rotation is as follows: 1. Whether the image is translated or rotated, the size and shape of the image itself are not changed, but only the position is changed, from one position to another.2. After the translation and rotation of the image, the corresponding line segment and Angle of the image will be equal.The difference between image translation and rotation is: 1. The trajectory of image translation is a straight line in the same direction, while the trajectory of rotation is an arc curve;2. After the translation of the image, the lines of the motion track of any point on the image will be parallel and equal, while the rotational motion track of the image is not equal and parallel, but the included Angle of each point’s motion is equal;3. A translation of an image moves from one point to another, while a rotation moves in a circle around a point or a line.After understanding the connection and difference between the translation and rotation of the image, please analyze the ferris wheel in the process of movement, does the person sitting on the ferris wheel do translation or rotation?Welcome to leave comments and discuss!Use your rich hands to give free likes and attention!Thank you!
