Across
  1. 5. A line that intersects with a plane at a point and is perpendicular to every line in the plane that intersects it at the point
  2. 7. A logical statement that has two parts: a hypothesis p and a conclusion q
  3. 8. A type of proof that uses boxes and arrows to show the flow of a logical argument
  4. 9. The statement formed by negating both the hypothesis and conclusion of the converseof the conditional statement
  5. 18. A statement that the values of two math expressions are equal
  6. 19. The opposite of a statement. If a statement is p, then the negation is "not p"
  7. 20. two related conditional statements that are both true or both false
  8. 22. A conditional statement in the form "if p, then q"
  9. 25. A type of proof that has numbered statements and corresponding reasons that show an argument in a logical order
  10. 26. A style of proof that presents the statements and reasons as sentences in a paragraph, using words to explain the logical flow of an argument
  11. 27. A flat surface made up of points that has two dimensions and extends without end. It is represented by a shape that looks like a floor or a wall
  12. 28. The "then" part of a conditional statement
  13. 29. A table that shows the truth values for a hypothesis, conclusion, and conditional statement
  14. 30. A specific case for which a conjecture is false
Down
  1. 1. A line has no dimension. It is represented by a line, with two arrowheads, but it extends without end
  2. 2. A statement that contains the phrase "if and only if"
  3. 3. Two lines that intersect to form a right angle
  4. 4. The statement formed by negating both the hypothesis and conclusion of a conditional statement
  5. 6. A process that uses facts, definitions, properties, and the laws of logic to form a logical argument
  6. 10. True T and false F
  7. 11. A mathmatical relationship or rule expressed in symbols
  8. 12. A rule that is accepted without proof
  9. 13. An unproven statement that is based on observations
  10. 14. The "if" part of a conditional statement
  11. 15. A process that includes looking for patterns and making conjectures
  12. 16. A location in space that is represented by a dot and has no dimension
  13. 17. A statement that can be proven
  14. 21. The statement formed by exchanging the hypothesis and conclusion of a conditional statement
  15. 23. A logical argument that uses deductive reasoning to show that the statement is true
  16. 24. To find the solutions that fulfill the condition stated by the equation
