A translation moves a shape by sliding it along the coordinate plane without changing its size or shape. The document describes moving shape A 3 squares to the right and then moving the new shape up 4 squares, labeling it B, as an example of performing a translation. Translations involve sliding shapes while preserving their dimensions.
