Question

use the diagram to the right. if ∠1 = ∠7, what theorem can you use to show that m||n?

Explanation:

When two lines are cut by a transversal and a pair of corresponding angles are congruent, the two lines are parallel. Here, ∠1 and ∠7 are corresponding angles. If ∠1 = ∠7, we can use the Corresponding - Angles Postulate which states that if corresponding angles formed by a transversal intersecting two lines are congruent, then the two lines are parallel.

Answer:

Corresponding - Angles Postulate
