Geometry Moves Without Turning Or Distorting
A geometric translation shifts every point of a shape by the exact same distance and direction. This process changes an object's location, but it never rotates, flips, or stretches the figure in any way.
Think of translation as sliding a puzzle piece across a table without lifting or spinning it. Because the shape remains identical in size and orientation, mathematicians call this an isometry. It is essentially a way to move an object through space while preserving its original structure. Whether you are moving a dot or a complex building blueprint, you are simply shifting its coordinates in a perfectly straight line.
