Please help this is hard

Answer 1

The sides that are congruent are sides AB and side DC

Answer 2

Hi!

Parallelograms have 4 sides. The parallel lines have equal lengths. 

Which means sides BC, and AD are equal. AB, DC are also equal. 

Only AB, DC are listed as an option so the answer is Sides AB and DC.

Hope this helps! :)
