There are 3 shapes on a 10x10 grid. Which shape is closest to the cyan 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: cyan trapezoid at (4, 1)
Distance from target shape to purple right_triangle at (2, 0): 3
Distance from target shape to gray trapezoid at (6, 8): 9
Closest shape is the purple right_triangle at (2, 0) with distance 3</think>
