Are the triangles similar? If so, what postulate or theorem proves their similarity?
O No, the triangles are not similar

Yes, by AA Similarity Postulate

O Yes, by SSS Similarity Theorem

O Yes, by SAS Similarity Theorem

second option I think is correct

Yes, by SSS Similarity Theorem

Step-by-step explanation:

the triangles are similar because the sides are proportional, the common ratio is 1.5.

if you look at the corresponding sides of the triangle and multiply 1.5 to the smaller triangle measurements, you get the bigger triangle's corresponding measurements:

3 * 1.5 = 4

4 * 1.5 = 6

6 * 1.5 = 9
