Answer: same side interior angles
Step-by-step explanation:
When two parallel lines are cut by a transversal, then the alternate interior angles , alternate exterior angles and corresponding angles are equal.
In case of same side interior angles,
The same-side interior angle theorem says that if two lines that are parallel are cut by a transversal then the same-side interior angles that are supplementary.
Hence, the correct answer is :same side interior angles "same side interior angles"
