Parallel Cut by Transversal and which lines are parallel

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

What are same side interior angles?

Back

Angles that are on the same side of the transversal and inside the two lines.

Front

If two lines are cut by a transversal and the same side interior angles are supplementary, what can be concluded?

Back

The two lines are parallel.

Front

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

Back

Corresponding angles are equal.

Front

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

Back

Alternate exterior angles are equal.

Front

If angle 1 and angle 3 are alternate interior angles, what can be said about the lines they are on?

Back

The lines are parallel if angle 1 is equal to angle 3.

Front

What is the sum of the measures of same side interior angles?

Back

They add up to 180 degrees.

Front

If angle 2 is 50 degrees, what is the measure of angle 6 if lines l and m are parallel?

Back

Angle 6 is also 50 degrees.

Front

What condition proves that line l is parallel to line m?

Back

If ∠2 ≅ ∠6.

Front

If angle 1 is 135 degrees, what is the measure of angle 3 if lines are parallel?

Back

Angle 3 is also 135 degrees.
