There are 5 shapes on a 5x5 grid. Which shape is closest to the pink 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: pink right_triangle at (0, 2)
Distance from target shape to orange square at (0, 1): 1
Distance from target shape to gray trapezoid at (4, 0): 6
Distance from target shape to brown right_triangle at (1, 1): 2
Distance from target shape to yellow trapezoid at (1, 3): 2
Closest shape is the orange square at (0, 1) with distance 1</think>
