Translations and Reflections on the Coordinate Plane

What does a translation on the coordinate plane involve?

• Flipping the object over an axis

• Changing the size of the object while keeping the position constant

• Moving the object to a new position without altering its size or orientation

• Rotating the object around a fixed point
