Question

translation, then reflection
rotation, then translation
translation, then rotation
rotation, then reflection

Explanation:

Step1: Observe the orientation change

We can see that the shape's orientation has changed from figure 1 to figure 2 and 3, which indicates a rotation has occurred first.

Step2: Observe the position change

After the rotation, the position of the shape has shifted on the grid, which implies a translation has taken place.

Answer:

rotation, then translation
