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 unite down
• a 90° clockwise rotation about the origin and then a translation 2 units up and 2 unite left
• a 180° rotation about the origin and then a translation 1 unit right
