Front

Define corresponding angles in the context of parallel lines cut by a transversal.

Back

Corresponding angles are pairs of angles that are in the same position at each intersection where a straight line crosses two others.

What is the definition of parallel lines?

Back

Parallel lines are lines in a plane that do not intersect or touch each other at any point.

Front

How do you determine if two lines are parallel using their slopes?

Back

If the slopes of two lines are equal, then the lines are parallel.
