Parallel Lines and Transversals Review for Flashcard

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

What are corresponding angles?

Back

Angles that are in the same position on two 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 two lines.

Front

What are consecutive interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

If two lines are parallel, what is true about their corresponding angles?

Back

They are equal.

Front

If two lines are cut by a transversal and the alternate interior angles are equal, what can be concluded?

Back

The lines are parallel.

Front

What is the sum of consecutive interior angles when the lines are parallel?

Back

180 degrees.

Front

How do you find the value of x that proves two lines are parallel?

Back

Set the corresponding or alternate interior angles equal to each other and solve for x.
