Question

Which of the following statement is correct?

(A) ∆BCD ≅ ∆CBA (SSS)

(B) ∆DCB ≅ ∆ABC (RHS)

(C) ∆ABC ≅ ∆DCB (SSS)​

Answer 1

Answer:

Solution

In △ABD and △BAC,

AD=BC (Given)

∠DAB=∠CBA (Given)

AB=BA (Common)

∴△ABD≅△BAC (By SAS congruence rule)

∴BD=AC (By CPCT)

And, ∠ABD=∠BAC (By CPCT)

please marked brain list

Answer 2

Answer:

ans = (b ) ∆DCB ≅ ∆ABC (RHS)
