Triangles a b c and x y z are shown. which would prove that δabc ~ δxyz? select two options. startfraction b a over y x = startfraction b c over y z endfraction = startfraction a c over x z endfraction startfraction b a over y x = startfraction b c over y z endfraction , angle c is-congruent-to angle z startfraction a c over x z endfraction = startfraction b a over y x endfraction , angle a is-congruent-to angle x startfraction b a over y x endfraction = startfraction a c over y z endfraction = startfraction b c over x z endfraction startfraction b c over x y endfraction = startfraction b a over z x endfraction , angle c is-congruent-to angle x.
