Geometry: Creating Parallel Lines and Transversals

Objectives

• Students will explore the angles formed when parallel lines are cut by a transversal by moving points F and D.
• Students will use informal arguments to establish facts about the angles created when parallel lines are cut by a transversal.

Vocabulary

• parallel
• transversal
• linear pair
• corresponding angles
• supplementary

About the Lesson

This activity is designed to be student-centered, with the teacher acting as a facilitator while students work cooperatively. The time varies for this activity depending on whether the TI-Nspire document (.tns file) is provided or created from scratch by the students.
