image attached. question: Can you prove that the two triangles are similar? Justify your answer.

my answer:
5/4 = 1.25

25/20 = 1.25

According to the SAS Similarity Postulate, the two triangles are similar, because two sides are proportional, and the included angles are congruent.

than you check the little image this angle is formed by sides with length 4 and 5 but in the biger image not is same - so in this case how you think can being similars ?

thesmartone · Answer

20 is the side opposite the angle
and for the other side, we have no value for the side opposite the angle

and so we can't create a proportion with the other sides since we aren't given any more information

So I guess I would have to answer that there isn't enough information to solve?  @TheSmartOne
