what did you get for # 7?

anonymous · Answer

I think it might be SSS, but I'm not sure @jim_thompson5910

jim_thompson5910 · Answer

well you have 2 sides, but the third side pairing isn't given

jim_thompson5910 · Answer

instead you have 2 sides and an angle in between them

jim_thompson5910 · Answer

which is why it's SAS

anonymous · Answer

Oh! Would the other one be not possible because it doesn't really give you anything?

jim_thompson5910 · Answer

no it's possible, maybe it's not as obvious as #7 though

anonymous · Answer

Wait no, I think it's AA

jim_thompson5910 · Answer

yep

jim_thompson5910 · Answer

you have a pair of vertical angles (which are congruent)

and one pair of alternate interior angles (which are congruent)
