Question

1. which angles are always congruent when formed by a transversal intersecting two parallel lines? a. consecutive interior angles b. adjacent angles c. alternate interior angles d. supplementary angles

Explanation:

When a transversal intersects two parallel lines, alternate - interior angles are always congruent. Consecutive interior angles are supplementary, adjacent angles formed by a transversal with parallel lines are not always congruent, and supplementary angles are two angles that add up to 180 degrees and are not always congruent to each other in the context of parallel lines and transversals.

Answer:

c. Alternate interior angles
