There are 6 shapes on a 8x8 grid. Which shape is closest to the orange 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: orange rectangle at (2, 0)
Distance from target shape to green right_triangle at (2, 2): 2
Distance from target shape to pink right_triangle at (1, 1): 2
Distance from target shape to red right_triangle at (5, 7): 10
Distance from target shape to purple square at (1, 4): 5
Distance from target shape to cyan trapezoid at (5, 2): 5
Closest shape is the green right_triangle at (2, 2) with distance 2</think>
