Answer:
Option# A: 3 and 6
Step-by-step explanation:
The line cutting the parallel lines a and b is called a Transversal. There is a theorem in mathematics for this scenario called, Alternate Interior angles theorem.
Alternate Interior Angles Theorem
"It states that, if two parallel lines are cut by a transversal, then the pair of alternate interior angles are congruent."
For our Case:
Line a and b are parallel, and the interior angles made by the transversal are 3, 4, 5 and 6, respectively. Here, 3 is the alternate angle of 6, as they are on the opposite side of the transversal. Similarly, 4 is the alternate angle of 5. Hence, 3 and 6 are congruent, and 4 and 5 are congruent.
As only 3 and 6 are present in the options, therefore, option# A is correct.
