Parallel Lines cut by a transversal

Front

What are parallel lines?

Back

Lines in a plane that never meet and are always the same distance apart.

Front

What is a transversal?

Back

A line that crosses at least two other lines.

Front

What are corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal.

Front

What are alternate interior angles?

Back

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

Front

What are same-side interior angles?

Back

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

Front

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

Back

They are congruent.

Front

If two parallel lines are cut by a transversal, what can be said about same-side interior angles?

Back

They are supplementary.

Front

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

Back

180 degrees.

Front

If angle 1 is 47 degrees, what is the measure of angle 3 if angle 1 and angle 3 are corresponding angles?

Back

47 degrees.
