Answer:
Step-by-step explanation:
SSS (Side-Side-Side) Postulate can be used to prove the two triangles congruent.
<u>Here's why:</u>
Whole figure is a parallelogram which means that opposite sides are parallel and equal (or congruent).
So, Two of the sides can be proved congruent by that way.
The third side is common in both of the triangles which means that the third side is also congruent.
Hence, the two triangles are congruent by SSS postulate.
Hope this helped!
