Looks like AAS only. @jim_thompson5910

jimthompson5910 (jim_thompson5910):

nope ASA also works too because we have these vertical angles marked in red

jimthompson5910 (jim_thompson5910):

actually now that I look it over again, AAS doesn't look like a good answer

jimthompson5910 (jim_thompson5910):

nvm I'm not thinking clearly. My initial thought still holds up. AAS works because you can determine the third angle but ASA is the faster route

DivineSolar (divinesolar):

ASA (Angle-Side-Angle) Postulate. If two angles and the included side of a triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.

So what do you think is right? @asadstep
