Your Friend claims that two isosceles triangles ABC and DEF are congrent if two corresponding sides are congruent. He explains that there are only two different lengths of sides, so if AB is congruent to DE and BC is congruent to Ef then it must follow that CA is congren to FD. Explain the error in his reasonin
