$in \: quadriateral \: acbd \\ ac = ad \: \\ ab \: bisects \: angle \: a \: \\ show \: that \: triangle \: abc \: is \: congruent \: to \: traingle \: abd \\ what \: can \: you \: say \: about \: bc \: and \: bd$
Answer this question​

Answer 1

Step-by-step explanation:

In ∆ABC and ∆ABD,

AC = AD (Given)

AB = AB (Common side)

∠DAB = ∠BAC (AB bisects ∠A)

therefore, ∆ABC ≅ ∆ABD (by S.A.S Criteria)

hence, proved!

BC = BD (by C.P.C.T)
