Question

For two parallel lines sum of the interior angles on the same side of the transversal is____(90°/120°/80°/180°)​

Answer 1

For two parallel lines sum of the interior angles on the same side of the transversal is 180°.

Step-by-step explanation:

When a transversal intersects two parallel lines then the interior angles on the same side of the transversal and exterior angles on the same side of the transversal are supplementary.*

*Supplementary : Two Angles are Supplementary when they add up to 180 degrees.
