11D Angles formed by Parallel Lines and a Transversal

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet. They are always the same distance apart and have the same slope.

What is a transversal?

Back

A transversal is a line that crosses at least two other lines in the same plane.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines.

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal.

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles that lie between two lines and on the same side of a transversal.

Front

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

Back

Same-side interior angles are supplementary, meaning they add up to 180°.
