SCCS Parallel Lines and Transversals

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 intersects two or more lines at different points.

Front

True or False: If two parallel lines are cut by a transversal, then consecutive exterior angles are congruent.

Back

False

Front

What are corresponding angles?

Back

Angles that are in the same position at each intersection where a transversal crosses two lines.

Front

What are alternate interior angles?

Back

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

Front

What are consecutive (same-side) interior angles?

Back

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

Front

If m∠8 = 48° and m∠2 is an alternate interior angle, what is m∠2?

Back

48°

Front

If two parallel lines are cut by a transversal, what is the relationship between alternate exterior angles?

Back

They are congruent.

Front

Solve for y: 2y + 10 = 80

Back

y = 35

Front

What is the sum of consecutive interior angles when two parallel lines are cut by a transversal?

Back

180°.
