An unproven statement that is based on observations | Conjecture |
Determining a pattern in specific cases and then writing a conjecture for the general case | Inductive reasoning |
A specific case for which a conjecture is false | Counterexample |
A logical statement that has two-parts a hypothesis and a conclusion | Conditional statement |
Most common way to write conditionals | If-then form |
Beginning part of a conditional | Hypothesis |
Ending part of a conditional | Conclusion |
A statement that is opposite the original statement | Negation |
Exchanging the hypothesis and conclusion of a conditional | Converse |
Negating both the hypothesis and conclusion of a conditional statement | Inverse |
Writing the converse of the conditional and then negating both the hypothesis and conclusion | Contrapositive |
When two statements are true or when two statements are false | Equivalent Statements |
Two lines intersecting to form a right angle | Perpendicular lines |
When both the conditional and converse are true | Biconditional statements |
Uses facts, definitions, accepted properties, logic, and rules to form a logical argument and reach a conclusion | Deductive Reasoning |
A statement involving the word and | Conjunction |
With a conjunction, what part of a venn diagram is shaded? | Only the overlapping region of both circles |
A statement involving the word or | Disjunction |
When one event or another event can be true but not both | Exclusive Disjunction |
When one event, another event, or both events could be true | Inclusive Disjunction |
With an exclusive disjunction, what part of a venn diagram is shaded? | Both circles, but not the overlapping |
With an inclusive disjunction, what part of a veen diagram is shaded? | Both circles and the overlapping |
