There are 4 shapes on a 3x3 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 (0, 2)
Distance from target shape to blue trapezoid at (2, 2): 2
Distance from target shape to purple trapezoid at (2, 0): 4
Distance from target shape to gray square at (0, 0): 2
Closest shape is the blue trapezoid at (2, 2) with distance 2</think>
