Answer: Parallel.
Step-by-step explanation:
Given: Lines a and c intersect at point S, creating 4 angles.
To Prove: Corresponding angles are congruent.
We are given that lines a and c intersect at point S.
Translate line a down line c until point S reaches point Q.
Call the new line through Q line b.
We know that translations preserve orientation then every point on line b is equidistant from every points on line a.
Therefore, lines a and b are parallel by the definition of parallel lines.
Hence, the complete statement is Because translations preserve orientation, lines a and b are parallel.
