There are 6 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 (3, 0)
Distance from target shape to brown rectangle at (3, 4): 4
Distance from target shape to pink square at (2, 2): 3
Distance from target shape to cyan right_triangle at (1, 1): 3
Distance from target shape to gray right_triangle at (2, 0): 1
Distance from target shape to purple rectangle at (3, 3): 3
Closest shape is the gray right_triangle at (2, 0) with distance 1</think>
