Angles formed by a Transversal

In this Chapter we will discover the angles that are formed when parallel lines are cut by a transversal. Such angles include: Corresponding, Vertical, Alternate-Interior, and Alternate-Exterior.

  • 1. Corresponding Angles
  • 2. Vertical Angles
  • 3. Alternate Interior Angles
  • 4. Alternate Exterior Angles
  • 5. Angles and Transversals
