Explains the proof that if a transversal intersects two parallel lines, then each pair of alternate angles are equal using proof of contradiction

Lesson Outcomes

• At the end of this lesson, the student will be able to:
• Define line, transversal, parallel lines, alternate interior angles, alternate exterior angles
• Identify alternate angles formed when a transversal intersects a pair of straight lines
• Understand the proof that If a transversal intersects two parallel lines, then each pair of alternate angles formed are equal using proof of contradiction
