Based on the given information, determine which sides of quadrilateral ABCD must be parallel.

Answer: The answer is A
Step-by-step explanation:I say that because if you think about it, the two 72 degree angles and 108 angles are the same to each other. Make a parallelogram and label A B C D along with the numbers for each and you'll see that line AB is parallel to line DC. Kind of a common sense question I guess. Hope this helps!
