Answer 1

Answer:

PLSS add me as brain list

Step-by-step explanation:

Step-by-step explanation:

Given

AB=DC and BC=AD

To prove

∆ABC congruent to ∆CDA

Proof

Given that AB=DC and BC=AD

So, ABCD is a parallelogram

we know that diagonal of a parallelogram divides it into two congruent triangles

therefore AC divides palagram ABCD into two congruent triangles

i.e ∆ABC≅∆CDA (PROVED)

OR

Consider ∆ABC and ∆CDA

AB=CD (Given)

BC=AD (Given)

AC=AC (Common)

So, ∆ABC ≅∆CDA (By SSS criteria)
