Identify which shapes on the graph are congruent to shape I by performing these sequences of transformations on shape I:

a reflection across the y-axis, followed by a 90° counterclockwise rotation about the origin, and then a translation 3 units down
a 90° counterclockwise rotation about the origin and then a translation 2 units up and 2 units left
a 180° rotation about the origin and then a translation 1 unit right
