There are 3 shapes on a 6x6 grid. Which shape is closest to the gray 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: gray right_triangle at (4, 4)
Distance from target shape to brown rectangle at (0, 3): 5
Distance from target shape to red trapezoid at (3, 2): 3
Closest shape is the red trapezoid at (3, 2) with distance 3</think>
