Question

1. the sum of the measures of consecutive interior angles when a transversal cuts through parallel lines is:

a. 180°
b. 300°
c. 270°
d. 90°

Explanation:

When a transversal intersects parallel lines, consecutive interior angles are supplementary. Supplementary angles sum to \(180^{\circ}\).

Answer:

A. \(180^{\circ}\)
