Studying for Test

Student Outcomes

  • Students know that corresponding angles, alternate interior angles, and alternate exterior angles of parallel lines are equal.  Students know that when these pairs of angles are equal, then lines are parallel.
  • Students know that corresponding angles of parallel lines are equal because of properties related to translation.  Students know that alternate interior angles of parallel lines are equal because of properties related to rotation.
  • Students present informal arguments to draw conclusions about angles formed when parallel lines are cut by a transversal.
