Question

Which congruency theorem can be used to prove that △ABD ≅ △DCA? SSS ASA SAS AAS

Answer 1

SAS is your answer I just had this question

Answer 2

Answer:

SAS

Step-by-step explanation:

Given: Two triangles ΔABD and ΔDCA,

We have, AD=AD (common)

               ∠A=∠A (Given)

                BA=CD (Sides opposite to equal angles are always equal)

With the SAS rule of congruency,

ΔABD≅ΔDCA
