There are 3 shapes on a 10x10 grid. Which shape is closest to the cyan trapezoid 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 trapezoid at (0, 0)
Distance from target shape to brown right_triangle at (1, 4): 5
Distance from target shape to red right_triangle at (9, 2): 11
Closest shape is the brown right_triangle at (1, 4) with distance 5</think>
