Provide an appropriate response.In triangle A, the longest side is twice as long as the shortest side. In triangle B, the longest side is also twice as long as the shortest side. If this is the only information you have about the two triangles, can you conclude that they must be similar? If you think that the two triangles must be similar, explain your answer. If you do not think that the triangles must be similar, sketch a counterexample.
