There are 6 shapes on a 9x9 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 (5, 1)
Distance from target shape to purple trapezoid at (4, 4): 4
Distance from target shape to yellow right_triangle at (4, 0): 2
Distance from target shape to green right_triangle at (5, 5): 4
Distance from target shape to brown rectangle at (7, 3): 4
Distance from target shape to blue right_triangle at (2, 3): 5
Closest shape is the yellow right_triangle at (4, 0) with distance 2</think>
