Proving Lines Parallel Check

Front

What is the Converse of Alternate Interior Angles Theorem?

Back

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

Front

What does the Converse of Same-Side Interior Angles Theorem state?

Back

If two lines are cut by a transversal and the same-side interior angles are supplementary, then the lines are parallel.

Front

What is the Converse of Corresponding Angles Postulate?

Back

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

Front

What does it mean if two angles are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines cross. They are always congruent.

Front

What is the definition of supplementary angles?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

What is the relationship between alternate interior angles and parallel lines?

Back

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

Front

What is the relationship between same-side interior angles and parallel lines?

Back

If two lines are parallel, then the same-side interior angles formed by a transversal are supplementary.

Front

How can you prove that two lines are parallel using corresponding angles?

Back

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

Front

What is the significance of the Vertical Angles Theorem in proving lines parallel?

Back

Vertical angles are congruent, which can help establish relationships between angles when proving lines are parallel.

Front

What does it mean if two angles are congruent?

Back

Two angles are congruent if they have the same measure.
