Hey Friends!!

Here is your answer↓⬇

⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇

▶⏩
 \huge \bf \sf{It \: is \: given \: that:-)}

↪➡
 \bf{AB = CD.}

↪➡
 \bf{ \angle \: ABD = \angle \: CDB .}

▶⏩
 \huge \bf \sf{To \: prove:-)}

↪➡

 \huge \boxed{AD = C B .}


 \bf \underline{Now, \: In \: \triangle \: ABD \: and \: \triangle \: CDB.}

 \bf{AB = CD ........(given).}

 \bf{ \angle \: ABD = \angle \: CDB.......(given).}

 \bf{BD = DB.........(common \: side).}

 \boxed{ = &gt; by \: SAS \: congruency \: rule}

 \huge \bf{ = &gt; \triangle ABD \cong \triangle CDB.}

 \boxed{AD = CB.......(CPCT).}

✅✅ Hence, it is proved ✔✔.

 \huge \boxed{THANKS}

 \huge \bf \underline{Hope \: it \: is \: helpful \: for \: you}

 \huge \bf{hey}

 \huge \: here \: is \: the \: answer
✔⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇✔✔✔✔✔

 \huge{given \: }
 \huge{ab = cd}

 \huge{angle \: abd = angle \: cbd}

 \huge{to \: prove \: ad = cb}

✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔

 \bf{in \: triangle \: abd \: and \: cbd}

 \bf{ad = cb (given)}

 \bf{angle \: abd = angle \: cbd(given) }

 \bf{bd = bd(common)}
hence

∆abd congruent ∆ cbd

hence

 \huge{ab = cd(cpct)}
 \huge \: hope \: it \: helps

 \huge \boxed{thanks}

Anonymous: bro u have done a mistake
Anonymous: in typing, it's AD = CB not AB = CD.
