Transforamtions:
Congruence means identical and transformation means change. Even though a shape has changed position (transformed), it still has the same shape and size (congruence).

Translation (sliding) is moving a shape without rotating or flipping it. The shape still looks exactly the same, just in a different place.
An image or shape as it would be seen in a mirror (flip).
