There are 6 shapes on a 9x9 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 blue rectangle at (1, 0): 2
Distance from target shape to brown square at (2, 0): 3
Distance from target shape to orange trapezoid at (2, 3): 2
Distance from target shape to gray rectangle at (4, 7): 8
Distance from target shape to yellow rectangle at (5, 6): 8
Closest shape is the blue rectangle at (1, 0) with distance 2</think>
