  2. 8. two lines that never touch
  3. 9. angles in the same relative position
  4. 12. adjacent angles formed by intersecting lines that add up to 180 degrees
  5. 13. angles outside the parallel lines and on the same side of the transversal
  6. 14. angles inside the parallel lines and on the same side of the transversal
Down
  1. 1. angles outside the parallel lines and on opposite sides of the transversal
