There are 6 shapes on a 5x5 grid. Which shape is closest to the cyan rectangle 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 rectangle at (3, 2)
Distance from target shape to pink square at (0, 4): 5
Distance from target shape to green right_triangle at (1, 1): 3
Distance from target shape to gray square at (0, 0): 5
Distance from target shape to yellow right_triangle at (3, 3): 1
Distance from target shape to red square at (4, 2): 1
Closest shape is the yellow right_triangle at (3, 3) with distance 1</think>
