Angle Relationships: Transversals and Parallel Lines

Investigating angle relationships formed by parallel lines and a transversal (e.g., corresponding, alternate interior, consecutive interior angles).

Key Questions

  1. Explain the relationships between different pairs of angles formed by a transversal intersecting parallel lines.
  2. Predict the measure of unknown angles given one angle in a transversal diagram.
  3. Construct a proof for why alternate interior angles are equal.
