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