Proving Lines Parallel Check

Front

What is the Converse Alternate Interior Angle Theorem?

Back

If two lines are cut by a transversal and the alternate interior angles are congruent, then the lines are parallel.

Front

What is the Converse Corresponding Angle Postulate?

Back

If two lines are cut by a transversal and the corresponding angles are congruent, then the lines are parallel.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What is the definition of a transversal?

Back

Front

What is the relationship between corresponding angles when two lines are parallel?

Back

Corresponding angles are congruent.

Front

What is the relationship between consecutive interior angles when two lines are parallel?

Back

Consecutive interior angles are supplementary.

Front

If m∠7 + m∠8 = 180°, what can be concluded about the lines cut by transversal n?

Back

The lines are parallel.

Front

What does it mean if ∠2 ≅ ∠6?

Back

It indicates that the lines cut by the transversal are parallel.

Front
