In this lesson on parallel and perpendicular lines, the instructor explains the differences between these two types of lines and how to determine whether lines are parallel or perpendicular. The lesson also covers how to write parallel and perpendicular equations, and how to find slopes of lines to identify relationships between parallel and perpendicular lines. The instructor demonstrates how to use this information to solve application problems and provides helpful tips and examples throughout the lesson.
