Best ResponseYou've already chosen the best response.1The first one is not similar because the sides are not in proportion. 3 can correspond to the 6 (x2) but if you apply the same thing to the 2 (2x2=4), you don't get 5. So they're not similar

Best ResponseYou've already chosen the best response.1For the 2nd one, 10+5=15 and 14+7=21. 10 and 14 (sides of the other triangle) relate to 15 and 21 because 10/14=15/21. You know this cuz you can simplify them both to 5/7

Best ResponseYou've already chosen the best response.1Oh. The similarity theorem is always by AA. SSS is if the numbers for the triangles are the same because it proves that the triangles are congruent.

Best ResponseYou've already chosen the best response.1As for your problem, it would be AA because you see that 2 angles are already congruent and you know that there's another set of congruent angles by (Vertical angles are congruent)
