There are 3 shapes on a 10x10 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 (4, 4)
Distance from target shape to blue trapezoid at (4, 0): 4
Distance from target shape to gray right_triangle at (7, 7): 6
Closest shape is the blue trapezoid at (4, 0) with distance 4</think>

<answer>(4, 0)</answer>
