A translation moves a shape.
A translation is a slide of a shape: without rotating, reflecting or resizing it.
A translation is a type of transformation.
A Real Example of a Translation
It is easier to understand translation with an example.
The diagram below shows a translation of a shape. The shape before the translation (called the object) is in light blue. The shape after the translation (called the image) is in dark blue:
In a translation,

a shape can move up

a shape can move down

a shape can move left

a shape can move right
In our example, the shape has moved 2 squares down and 2 squares right
Each point on the shape moves the same direction and the same distance.
Choose any point on the object. It has been moved 2 squares down and 2 squares right in the image.
