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. <ABC and <FCB are same-side interior anlges. Name another pair of same-side interior angles.
3. What is always true about same-side interior angles formed when parallel lines are intersected by a transversal?
4. Prove your conjecture from question #3.
