Setting up 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 intersects two or more lines at different points.

Front

What is the sum of the interior angles on the same side of a transversal?

Back

180 degrees.

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 alternate exterior angles?

Back

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

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

They are equal.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

They are equal.

Front

What is the relationship between alternate exterior angles when two parallel lines are cut by a transversal?

Back

They are equal.

Front

How do you set up an equation for angles formed by a transversal?

Back

Identify the relationships (e.g., corresponding, alternate interior) and set them equal or sum them to 180 degrees.
