There are 5 shapes on a 5x5 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 (2, 2)
Distance from target shape to pink rectangle at (2, 0): 2
Distance from target shape to brown trapezoid at (1, 0): 3
Distance from target shape to purple right_triangle at (1, 1): 2
Distance from target shape to yellow rectangle at (0, 4): 4
Closest shape is the pink rectangle at (2, 0) with distance 2</think>
