Across
  1. 3. angle An angle that measures more than 90 degrees but less than 180 degrees
  2. 6. angles two angles that add up to 90 degrees
  3. 7. A figure formed by two rays with a common endpoint
  4. 8. points that lie on the same line
  5. 9. angle an angle that measures 90 degrees -- perpendicular
  6. 10. a statement that is believed to be true but not yet proven
  7. 11. a statement that is accepted as true without requiring proof
  8. 14. Statement ~q -> ~p, It is formed by reversing AND negating the hypothesis and the conclusion of the conditional to become "if not q, then not p".
  9. 15. segment part of a line with two endpoints
  10. 18. points that lie on the same plane
  11. 20. Having the same measure
  12. 21. Statement ~p -> ~q, A conditional statement that negates the hypothesis and conclusion. If not p then not q.
  13. 24. points that do not lie on the same plane
  14. 25. distance the length of a specific part of a line
  15. 26. a straight path that has no thickness and extends in both directions infinitely -- undefined term
  16. 27. a statement that can be proven
  17. 28. rays two rays that share the same endpoint and form a line
  18. 30. angle an angle that measures exactly 180 degrees
Down
  1. 1. an example that proves that a conjecture or statement is false
  2. 2. statement p -> q, a statement that can be written in if-then form
  3. 4. statement p <-> q, A statement that contains the phrase "if and only if"
  4. 5. A point that divides a segment into two segments of equal length.
  5. 12. angles two angles that add up to 180 degrees
  6. 13. points that do not lie on the same line
  7. 16. A part of a line, with one endpoint, that continues infinitely in one direction
  8. 17. a point at an end of a segment or the starting point of a ray
  9. 19. angle an angle that measures less than 90 degrees
  10. 22. Statement q -> p, the statement formed by exchanging the hypothesis and conclusion of a conditional statement
  11. 23. a flat surface that has no thickness and extends forever -- undefined term
  12. 29. A location in space that is represented by a dot and has no dimension -- undefined term
