Corresponding Angles

Lines AB and FC are parallel. Line BC is a transversal.
1. Use points A, B, and C to move the lines. Observe the angle values. 2. <ABE and <FCB are corresponding anlges. Name another pair of same-side interior angles. 3. How many pairs of corresponding angles are there? 4. What is true about corresponding angles formed when parallel lines are cut by a transversal?
