Answer:
SAS
Step-by-step explanation:
Here, we want to check for if the triangles are similar
Firstly, we notice a marked angle on both triangles
This shows that we have an angle that is similar in both triangles
Also, if we check, we can deduce that the bigger looks like a scaled version of the smaller one to a tune of 3
This means that the sides of the smaller when multiplied by 3 gave the bigger
since the sides are in proportion, then the triangles are similar. It is not alone that the sides must be equal; once they are in proportion, then the triangles are similar triangles
