Translation refers to the movement of mathematical figures along a straight line for a certain distance in the same plane, which is called the translation movement of mathematical figures.

Translation does not change the shape and size of the graph,

The translated figure is parallel (or on the same straight line), which is equal to the line segment connected with the corresponding point on the original figure.

It is equidistant isomorphism and an affine transformation in affine space.

You can think of it as adding the same vector to each point and then moving these vectors.

Or move the center of the coordinate system.
