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 <FCG are same-side exterior anlges. Name another pair of same-side exterior angles.
3. What is always true about same-side exterior angles formed when parallel lines are cut by a transversal?
4. Prove your conjecture from question 3.
