There are 3 shapes on a 10x10 grid. Which shape is closest to the red 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: red trapezoid at (1, 9)
Distance from target shape to green trapezoid at (0, 5): 5
Distance from target shape to orange trapezoid at (2, 8): 2
Closest shape is the orange trapezoid at (2, 8) with distance 2</think>

<answer>(2, 8)</answer>
