Answer:
Translation or Reflection
Explanation:
A translation is moving and shape on a coordinate plan without altering it in anyway so you could use translation to do so if the orientation of the shape doesn't change. However, It could also be a reflection. Since I can't see the movement I cannot tell you which one it is. A reflection flips a shape on a plane over any line (including x & y axis) so if the shape looks like its been picked up and flipped over its a reflection if you provide a picture of the grid I can tell you which one it is for sure
