Parallel Lines and Transversals

Front

What is the angle pair name for angles that are on the same side of the transversal and between the two parallel lines?

Back

Same side interior angles.

Front

What is the angle pair name for angles that are on opposite sides of the transversal and between the two parallel lines?

Back

Alternate interior angles.

Front

What is the angle pair name for angles that are on opposite sides of the transversal and outside the two parallel lines?

Back

Alternate exterior angles.

Front

What is the angle pair name for angles that are on the same side of the transversal and outside the two parallel lines?

Back

Same side exterior angles.

Front

If two parallel lines are cut by a transversal, what can be said about the corresponding angles?

Back

Corresponding angles are equal.

Front

If angle 4 measures 50 degrees, what is the measure of angle 6 if lines are parallel?

Back

Angle 6 measures 50 degrees (same side interior angles are supplementary).

Front

What is the relationship between vertical angles when two lines intersect?

Back

Vertical angles are equal.

Front

If angle 5 is 65 degrees, what is the measure of angle 4 if lines are parallel?

Back

Angle 4 measures 115 degrees (same side interior angles are supplementary).

Front

What is the sum of the interior angles on the same side of the transversal when two parallel lines are cut?

Back

The sum is 180 degrees.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.
