There are 5 shapes on a 6x6 grid. Which shape is closest to the pink 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: pink right_triangle at (1, 1)
Distance from target shape to orange rectangle at (0, 2): 2
Distance from target shape to purple trapezoid at (4, 4): 6
Distance from target shape to yellow trapezoid at (4, 1): 3
Distance from target shape to green rectangle at (3, 0): 3
Closest shape is the orange rectangle at (0, 2) with distance 2</think>
