1. conjecture
unproven statement based on observations
2. inductive reasoning
when you find a pattern in specific cases and then write a conjecture for the general case
3. counterexample
specific case for which a conjecture is false
4. conditional statement
• logical statement that has 2 parts
• hypothesis
• conclusion
5. if then form
when conditional statement is proven
6. converse
• switch original
• exchange hypothesis and conclusion
7. inverse
negative original
8. contrapositive
converse negative
9. equivalent statement
when 2 statements are both true or both false
10. perpendicular
if two lines intersect to form a right angle
11. biconditional
statement that contains if and only if
12. deductive reasoning
using facts, definitions, and laws of logic
13. line perpendicular to a plane
the line intersects the plane in a point and is perpendicular to every line in the plane that intersects it at that point
14. proof
logical argument that shows a statement is true
15. two-column proof
numbered statements and corresponding reasons that show an argument in a logical order
16. theorem
statement that can be proven
17. complementary angles
