Question Analysis

This question involves identifying the relationship between same-side interior angles. The main focus is on understanding the properties of parallel lines cut by a transversal.

Key Concept Explanation:

When two parallel lines are cut by a transversal: same-side interior angles lie on the same side of the transversal and inside the parallel lines, and they are supplementary (add up to 180°).

Congruent angles are equal in measure.

Complementary angles add up to 90°.

Supplementary angles add up to 180°.

Step-by-Step Solution:

When two parallel lines are cut by a transversal, same-side interior angles are supplementary (add up to 180°).
