  2. 4. exterior angles non adjacent and on opposite sides of the transversal
  3. 7. has aproximatley the same
  4. 8. if <a is complimentary to <b and <c is complimentary to <b then <a is congruent to <c
  5. 9. if a=b and b=c then a=c
  6. 10. if 2 angles are vertical they are congruent
  7. 11. if a=b then b=a
