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