Answer: Fifth option is correct.
Explanation:
Since we have given that
l and m are two parallel lines in which there is a transversal.
When a transversal cuts the parallel lines, it forms corresponding angles.
Corresponding angles are those angles that occurs the same position at an intersection where transversal cut the parallel lines.
and corresponding angles are equal in measure.
Similarly, ∠5 and ∠7 forming corresponding angles.
Hence, Fifth option is correct.
