Hi, I'm trying not to loose my mind on this problem. It doesn't make any sense to me, I've been trying to figure it ot for 2 hours. Can anyone help?

Problem 1:

Question: Which lines, if any, must be parallel based on the given information? Justify your conclusion.

Given: 11 is congruent to 3.

Multiple answers:
a || b, Converse of the Alternate Exterior Angles Theorem

c || d, Converse of the Same-Side Interior Angles Theorem

a || b, Converse of the Corresponding Angles Postulate

Not enough information to make a conclusion.

Problem 2:

Given 3 is congruent to 13.
