There are 6 shapes on a 6x6 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 (4, 2)
Distance from target shape to blue square at (1, 0): 5
Distance from target shape to yellow right_triangle at (5, 4): 3
Distance from target shape to brown rectangle at (4, 5): 3
Distance from target shape to green square at (0, 2): 4
Distance from target shape to red trapezoid at (2, 0): 4
Closest shape is the yellow right_triangle at (5, 4) with distance 3</think>
