There are 5 shapes on a 9x9 grid. Which shape is closest to the red square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: red square at (0, 2)
Distance from target shape to gray right_triangle at (2, 2): 2
Distance from target shape to orange right_triangle at (4, 5): 7
Distance from target shape to yellow rectangle at (7, 2): 7
Distance from target shape to pink right_triangle at (3, 1): 4
Closest shape is the gray right_triangle at (2, 2) with distance 2</think>
