- 1Deductive ReasoningA process of reasoning that uses facts, logic, and/or postulates to draw a conclusion.
- 2Inductive ReasoningA process of reasoning that a rule or statement is true because specific cases, such as observations or patterns, are true.
- 3ConjectureA statement that is believed to be true.
- 4Adjacent AngleTwo angles with a common side and vertex. They cannot overlap.
- 5Supplementary AnglesTwo angles whose measures add up to 180 degrees.
- 6Complementary AnglesTwo angles whose measures add up to 90 degrees.
- 7Linear PairA pair of adjacent angles whose non-common sides are opposite rays.
- 8CongruentTwo figures that are the same size and shape.
- 9TheoremA statement that can be proven true through a series of logical steps.
- 10Linear Pair TheoremIf two angles form a linear pair, then they are supplementary.
- 11Conditional StatementA sentence written in if/then format. Shown by p -> q
- 12HypothesisAn educated guess. Demonstrated by p.
- 13ConclusionThe "answer" to a hypothesis. Demonstrated by q.
- 14NegationThe opposite of a hypothesis or a conclusion. Demonstrated by ~p or ~q.
- 15ConverseThe opposite of a conditional statement. Shown by q <- p.
- 16InverseThe reverse of a conditional statement. Shown by ~p -> ~q.
- 17ContrapositiveThe reverse of a converse. Shown by ~q <- p.
- 18BiconditionalA sentence used if and only if a conditional statement and the converse are true. Uses an if and only if format. Demonstrated by p <-> q.
- 19CounterexampleA sentence that proves a conditional, converse, inverse, or contrapositive to be incorrect. Only one counterexample is needed to prove a statement false.
- 20Truth TableA table used to demonstrate conditionals, converses, inverse and contrapositives and if they are true or false.
- 21ConjunctionA statement that can only be true if both p and q are true. It is an and statement demonstrated with a ⋀.
- 22DisjunctionA statement that can only be false if both p and q are false. It is an or statement demonstrated with a ⋁.
