Rigid Motions Without Coordinate Plane

What is translation in geometry?

• Moving a shape or object without changing its size, shape, or orientation.

• Changing the size of a shape or object without moving it.

• Reflecting a shape or object over a line without changing its size or position.

• Rotating a shape or object without changing its size or position.
