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