TermDefinition
biconditional Is a statement in which both the conditional statement and it's converse are true.
conclusion The part of a conditional statement following the "then".
conditional A statement written in if-then form.
conjecture A conclusion you reach using inductive reasoning.
contrapositive Exchange and negate both the hypothesis and the conclusion of a conditional statement -q --> -p
converse Exchange the hypothesis and conclusion of a conditional statement. q --> p
counterexample An example that shows that a conjecture is false.
deductive reasoning Is the process of reasoning logically from given statements, facts, definitions, or theorems to a conclusion.
equivalent statements Two statements that have the same truth value.
hypothesis The part of a conditional statement following the If.
inductive reasoning Reasoning based on patterns you observe.
inverse Negate both the hypothesis and the conclusion of a conditional statement......-p --> -q
Law of Detatchment Logical reasoning in which ...if the hypothesis of a true conditional is true then the conclusion must also be true.
Law of Syllogism Logical reasoning which...allow you to state a conclusion from TWO true conditional statements in when the conclusion of one statement is the hypothesis of the other statement.
negation the opposite of a statement p is ~p which is read "not p".
proof A convincing argument that uses deductive reasoning which shows logically why a conjecture is true.
theorem is a conjecture or statement that has been (or can be) proven true using deductive reasoning.
truth value A conditional statement can be either a true or a false statement.
two column proof A proof which has two columns, it gives each statement on the left and the reason for each statement on the right.
addition property of equality if a = b then a+c = b+c
subtraction property of equality if a=b then a-c=b-c
multiplication property of equality if a=b then ac = bc
division property of equality if a=b then a/c =b/c (given c does not equal 0)
Reflexive Property a=a
Symmetric Property If a=b then b=a
Transitive Property If a=b and b=c then a=c
Substitution Property If a=b then b can replace a in any expression
Distributive Property of multiplication over addition a(b+c) = ab + ac
