Answer:
C) Not enough information or not similar.
Explanation:
Actually, those figures don't provide enough information to know is they can be similar, and we cannot know which postulate can be used to demonstrate such similarity.
To demonstrate a similarity by SSS, we need a proportionality between all corresponding three side, which we don't have because we don't know about the measure of neither side.
To demonstrate it by AA, we need the congruence between two corresponding triangles, which we don't have, the image doesn't provide it.
To demonstrate it by SAS, we need the congruence of one corresponding angle, and the proportion between two corresponding sides, we also don't have in this case.
Therefore, the right answer would be C.
