Ab ? bc and ad ? cd what additional information would make it immediately possible to prove that triangles axb and cxb are congruent using the hl theorem? bx and dx are congruent. ax and cx are congruent. ac and bd are perpendicular. bd bisects angle abc what additional information would make it immediately possible to prove that triangles axd and cxd are congruent using the sss congruence theorem? bx and dx are congruent. ax and cx are congruent. ac and bd are perpendicular. bd bisects angle adc

it is given that, b ≅ bc and ad ≅ cd  

we need bd perpendicular to ac, then only we can say   triangles axb and cxb are congruent using the hl theorem.

if bd perpendicular to ac, means that ab and cb are the hypotenuse of triangles axb and cxb respectively.

from the given information abcd is a square

if bd and ac bisect each other then ax = cx

then only we can   immediately possible to prove that triangles axd and cxd are congruent by sss congruence theorem.
