Common Mistakes
✗ Wrong: Co-interior angles are equal
✓ Right: Co-interior angles ADD to 180° (they're supplementary)
✗ Wrong: Forgetting to check if lines are actually parallel
✓ Right: These rules ONLY work for parallel lines
✗ Wrong: Not giving a reason in the answer
✓ Right: State "corresponding/alternate/co-interior angles on parallel lines"
