Explains the proof that if a transversal intersects two lines such that a pair of the co-interior angles formed add up to 180 degrees, then the given pair of lines are parallel

Lesson Outcomes

• At the end of this lesson, the student will be able to:
• Define line, transversal, parallel lines, co-interior angles
• Understand the proof that if a transversal intersects two lines such that a pair of the co-interior angles formed add up to 180 degrees, then the given pair of lines are parallel by method of contradiction
