Question

when parallel lines are cut by a transversal: alternate interior angles - are congruent alternate exterior angles - are congruent corresponding angles - are congruent same - side interior angles - are supplementary (add to 180) same - side exterior angles - are supplementary (add to 180) what type of angles are ∠3 & ∠6? alternate interior angles are these angles congruent or supplementary? select if m∠3 = 60, find ∠6 select

Explanation:

Step1: Recall angle - property

When parallel lines are cut by a transversal, alternate interior angles are congruent. Since $\angle3$ and $\angle6$ are alternate interior angles, they are congruent.

Step2: Use congruency to find angle measure

If $m\angle3 = 60$ and $\angle3\cong\angle6$, then $m\angle6=60$.

Answer:

1. Congruent
2. 60
