 Two identical equilateral triangles, A and B, each have a line segment connecting the midpoints of two sides. Triangle A is moved horizontally to the right until the two triangles overlap and then continue moving apart. At the position where the number of triangles is maximized, how many triangles are there in the figure? Express your answer as a single integer. Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
