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 intersects two or more lines at different points.

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.

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

Back

If the corresponding angles are equal, then the two lines are parallel.

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

Back

The sum of the interior angles on the same side of a transversal is 180 degrees.
