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