  1. 5. a statement or conjecture that has been proven
  2. 6. used to find the distance between two points on the coordinate plane
  3. 7. two lines in the same plane that never intersect
  4. 10. describes the relationship between the lengths of the legs and the hypotenuse for any right triangle

  2. 2. exterior angles that lie on opposite sides of the transversal
  3. 3. a type of formal proof that contains statements and reasons organized into columns
