There are 4 shapes on a 6x6 grid. Which shape is closest to the orange trapezoid 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 trapezoid at (0, 0)
Distance from target shape to green square at (5, 2): 7
Distance from target shape to pink right_triangle at (2, 2): 4
Distance from target shape to cyan rectangle at (4, 2): 6
Closest shape is the pink right_triangle at (2, 2) with distance 4</think>
