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 (6, 8)
Distance from target shape to green right_triangle at (9, 8): 3
Distance from target shape to brown right_triangle at (2, 7): 5
Closest shape is the green right_triangle at (9, 8) with distance 3</think>

<answer>(9, 8)</answer>
