  1. Coplanar lines that do not intersect
    Parallel lines
  2. A line that intersects two or more coplanar lines at different points
    Traversal
  3. 4 Different types of angles formed by transversals:
    • Corresponding
    • Alternate interior
    • Alternate Exterior
    • Consecutive Interior

  4. 2 and 7 are examples of what?
    Alternate Interior Angles

  5. 2 and 3 are examples of what?
    Consecutive Interior Angles

  6. 5 and 7 are examples of what?
    Corresponding Angles

  7. 2 and 4 are examples of what?
    Corresponding angles

  8. 5 and 8 are examples of what?
    Alternate Exterior Angles
  9. What do you need to do when you need to find the value of x that makes two lines parallel and the angles are corresponding?
    You set them equal to each other
  10. When you  need to explain why to lines are parallel does a Corresponding angle have a theorm or a postulate?
    Postulate
  11. When you  need to explain why to lines are parallel does a Alternate Exterior Angle angle have a theorm or a postulate?
    Theorm
  12. When you  need to explain why to lines are parallel does a Alternate Interior angle have a theorm or a postulate?
    Theorm
  13. When you  need to explain why to lines are parallel does a Consecutive Interior angle have a theorm or a postulate?
    Theorm
  14. When trying to explain why something is parallel how would you word it if the angles were:
    Alternate Exterior Angles
    They are parallel because of the Alternate Exterior Angle Theorm Converse
  15. When trying to explain why something is parallel how would you word it if the angles were:
    Corresponding Angles
    They are parallel because of the Corresponding Angle Postulate Converse
  16. Angles that lie outside of the two lines are on opposite sides of the transversal
    Alternate Exterior Angles
  17. Angles that lie between the two lines and are on opposite sides of the transversal
    Alternate Interior Angles
  18. Angles that are between the two lines and are on the same side of the transversal
    Consecutive Interior Angles
  19. If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent
    Corresponding Angle Postulate
  20. If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent
    Alternate Interior Angle Theorem
  21. If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent
    Alternate Exterior Angle Theorem
  22. If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary
    Consecutive Interior Angle Theorem
  23. What is true about Vertical Angles and Corresponding angles?
    their values are always the same.
  24. A statement made in the if-then form
    Conditional Statement
  25. What is a converse?
    When you switch the hypothesis and the conclusion
  26. When do you need to give credit to why the angles are parallel to Angle Addition Postlate?
    When you add in an angle
