- Corresponding angles
- Co-interior angles
- Alternate angles
Task goals
- Identify corresponding, alternate, and co-interior angle pairs formed by a transversal crossing a pair of parallel lines.
- Find an unknown angle using the corresponding angles rule (equal angles).
- Find an unknown angle using the alternate angles rule (equal angles).
- Find an unknown angle using the co-interior angles rule (angles sum to 180 degrees).
- Combine a parallel-line angle rule with vertically opposite angles to find an unknown angle.
- Form and solve an equation from an algebraic angle expression using the correct parallel-line rule.
- Name the angle rule used to justify a found angle.
- Decide whether a described pair of angles proves that two lines are parallel.
