It is a translation phenomenon that people push boxes. This is the knowledge point of "figure and transformation" in "figure and geometry" in primary school mathematics.

Translation means that all points on the map move equidistantly along a straight line in the same plane. This kind of graphic movement is called graphic translation movement, which is called translation for short.

Translation does not change the shape and size of the graph. After translation, the corresponding line segments are equal, the corresponding angles are equal, and the line segments connected by the corresponding points are equal. It is equidistant isomorphism and an affine transformation in affine space. It can be considered as the result of adding the same vector to each point or moving the center of the coordinate system. That is, if a known vector is a point in space, translate.

The role of translation:

1. Fine graphics can be built by simple translation. That is, lace is usually used for decoration, and the process is copy-translation-paste.

2. Translation is often related to parallel lines. Translation can translate an angle, a line segment and a figure to another position, which is the concentration of scattered conditions on a figure, thus solving the problem.
