Question

lines l and m are intersected by transversal t and l || m. by which postulate or theorem is ∠3 ≅ ∠6? a. alternate exterior angles theorem b. alternate interior angles theorem c. corresponding angles theorem d. same - side interior angles postulate

Explanation:

$\angle3$ and $\angle6$ are non - adjacent angles that lie between the two parallel lines $\ell$ and $m$ and on opposite sides of the transversal $t$. The Alternate Interior Angles Theorem states that when two parallel lines are cut by a transversal, the alternate interior angles are congruent.

Answer:

B. Alternate Interior Angles Theorem
