There are 3 shapes on a 3x3 grid. Which shape is closest to the cyan rectangle in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: cyan rectangle at (0, 0)
Distance from target shape to green right_triangle at (1, 1): 2
Distance from target shape to purple rectangle at (2, 2): 4
Closest shape is the green right_triangle at (1, 1) with distance 2</think>
