On the Diophantine system involving pairs of triangles with the same area and the same perimeter
Yangcheng Li, Yong Zhang
Many authors studied the problem that rational triangle pairs (triangle-parallelogram pairs) with the same area and the same perimeter. They investigated this problem by solving th…
