Geometry

Question Analysis:
This tests knowledge of angle relationships in trapezoids.
The main focus is on same-leg interior angles.

Key Concept Explanation:
When two lines are parallel, same-leg interior angles are supplementary.

Step-by-Step Solution:
In trapezoids, parallel bases make interior angles add to 180°.

Option Analysis:
A. Incorrect – not equal
B. Correct – Supplementary due to parallel lines
C. Wrong type...
