There are 6 shapes on a 10x10 grid. Which shape is closest to the gray 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: gray square at (2, 0)
Distance from target shape to green square at (1, 6): 7
Distance from target shape to purple square at (7, 9): 14
Distance from target shape to blue right_triangle at (8, 0): 6
Distance from target shape to brown square at (3, 8): 9
Distance from target shape to pink right_triangle at (8, 8): 14
Closest shape is the blue right_triangle at (8, 0) with distance 6</think>
