what are your thoughts on this @osoneedshelp ?

anonymous · Answer

@jim_thompson5910 i think it might be B

jim_thompson5910 · Answer

do we know that all 3 pairs of sides are proportional?

anonymous · Answer

No? @jim_thompson5910

jim_thompson5910 · Answer

We don't. We only know info about 1 pair of sides (not 3)

so we can't use SSS

jim_thompson5910 · Answer

We can't use SAS either because, again, we only know info about 1 pair of sides (not 2 pairs)

jim_thompson5910 · Answer

and we can't use AA because we only know 1 pair of angles are congruent (the 90 degree angles). But we don't know anything about any other pair of angles
