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