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 (2, 8)
Distance from target shape to orange right_triangle at (3, 4): 5
Distance from target shape to yellow square at (0, 3): 7
Closest shape is the orange right_triangle at (3, 4) with distance 5</think>
