Questions and Answers

What does the Law of Detachment state?

If the hypothesis of a true conditional statement is true, then the conclusion is also true. (correct)

The process of using logic to draw conclusions from given facts.

If a car is a corvette, then it is a Chevrolet.

If p-->q and q-->r are true, then p-->r is also true.

What does the Law of Syllogism assert?

The process of using logic to draw conclusions.

If p-->q and q-->r are true statements, then p-->r is a true statement. (correct)

If a figure is a kite, then it is a quadrilateral.

If the hypothesis of a true conditional is true, then the conclusion is true.

Study Notes

Geometry Laws Overview

Law of Detachment: If a true conditional statement's hypothesis is true, the conclusion also holds true.
Law of Syllogism: If two true conditional statements (p→q and q→r) exist, then a new true statement (p→r) can be derived.

Examples

Law of Detachment Example:
- Given: "If a car is a corvette, then it is a Chevrolet."
- Fact: "Suzie's car is a Corvette."
- Conclusion: "Suzie's car is a Chevrolet."
Law of Syllogism Example:
- Given: "If a figure is a kite, then it is a quadrilateral."
- Given: "If a figure is a quadrilateral, then it is a polygon."
- Conclusion: "If a figure is a kite, then it is a polygon."

Deductive Reasoning

Deductive reasoning involves using logic to derive conclusions from established facts, definitions, and properties.

Combined Use of Laws

Combined Application:
- Given: "If you live in Fairbanks, then you live in Alaska."
- Given: "If you live in Alaska, then you live in the largest state in the U.S."
- Law of Syllogism Conclusion: "If you live in Fairbanks, then you live in the largest state in the U.S."
- Law of Detachment Conclusion: "Alan lives in the largest state in the U.S." (from the previous conclusion).
