There are 6 shapes on a 9x9 grid. Which shape is closest to the cyan right_triangle 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 right_triangle at (3, 0)
Distance from target shape to pink rectangle at (1, 5): 7
Distance from target shape to green trapezoid at (6, 5): 8
Distance from target shape to brown right_triangle at (8, 5): 10
Distance from target shape to yellow trapezoid at (5, 2): 4
Distance from target shape to purple square at (4, 5): 6
Closest shape is the yellow trapezoid at (5, 2) with distance 4</think>
