Bluebook Digital SAT Test 1 Module 2 (Hard) Question 22:

In triangles LMN and RST, angles L and Reach have measure 60°, LN = 10, and RT = 30. Which additional piece of information is sufficient to prove that triangle LMN is similar to triangle RST?

is the reason why choice B doesn’t work because there is no such thing as SSA in triangle congruence theorems? How do we know what is sufficient to prove triangle similarlity, should we be referring to the congruence theorems or the similarity postulates/theorems? Thank you for your amazing explanations!!

if the side LM = 7 and the side RS = 21, would this prove that they are similar? Because the angle 60º would be between the sides and i think it could prove the congruency by the Side-Angle-Side rule

hey, im the guy from the video where i said you complicated the question too much, if you can please post the video again so i can suggest something that i found works that would be great, also takes under 20 seconds to solve

do you have all sats from 1-10 videos?
