There are 6 shapes on a 7x7 grid. Which shape is closest to the cyan 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: cyan right_triangle at (1, 4)
Distance from target shape to pink right_triangle at (3, 5): 3
Distance from target shape to yellow trapezoid at (0, 4): 1
Distance from target shape to purple rectangle at (1, 5): 1
Distance from target shape to orange square at (4, 2): 5
Distance from target shape to blue square at (5, 6): 6
Closest shape is the yellow trapezoid at (0, 4) with distance 1</think>
