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