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