There are 6 shapes on a 6x6 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, 5)
Distance from target shape to purple trapezoid at (0, 3): 6
Distance from target shape to yellow rectangle at (1, 0): 8
Distance from target shape to green right_triangle at (3, 2): 4
Distance from target shape to orange trapezoid at (3, 1): 5
Distance from target shape to red rectangle at (1, 1): 7
Closest shape is the green right_triangle at (3, 2) with distance 4</think>
