Translations in the Coordinate Plane

Explore translations in the coordinate plane.
1. Drag Point G around the coordinate plane. [br]2. Describe the relationship between the length of the vector and the distance between A and A'.[br]3. Describe the relationship between the direction of the vector and the direction of the slide.[br]4. Is a translation an isometry (does it preserve the shape and size of the pre image)?
