Intro: Translations in the Coordinate Plane

This silent demo shows how to translate an object in GeoGebra. Watch this video, then translate Mona Lisa by vector u in the app below.

Use the TRANSLATE BY VECTOR Translate Mona Lisa's pic (and two base points) here.

In the app above, drag points B and C around. What do you notice? What do you wonder? Notice anything interesting? List anything you observe or that you find interesting.

In the app above, you ended up TRANSLATING Mona Lisa by a vector. How would you describe what it means to translate an object by a vector?
