There are 4 shapes on a 5x5 grid. Which shape is closest to the orange 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: orange right_triangle at (1, 0)
Distance from target shape to green right_triangle at (0, 3): 4
Distance from target shape to red right_triangle at (3, 2): 4
Distance from target shape to brown trapezoid at (2, 2): 3
Closest shape is the brown trapezoid at (2, 2) with distance 3</think>
