Ch 11: Holt Geometry Chapter 12: A Closer Look at Proof and Logic

About This Chapter

The proof and logic chapter of this Holt Geometry Textbook Companion Course helps students learn the essential geometry lessons of truth values, logic types, conditional statements and indirect proofs. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the proof and logic textbook chapter.

How it works:

  • Identify the lessons in Holt Geometry's A Closer Look at Proof and Logic chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the geometry proof and logic topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Propositions, truth values and truth tables
  • Logical fallacies
  • Logical math connectors
  • Conditional statements in mathematics
  • Parallel postulate and indirect proof
  • Programming logic and syntax
  • Boolean logic, operators and expressions

Propositions, Truth Values and Truth Tables

1. Propositions, Truth Values and Truth Tables

Watch this video lesson and learn what truth values are and what a truth table looks like. Learn how to go from a proposition to its negation and how that affects the truth values and the truth tables.

Logical Fallacies: Hasty Generalization, Circular Reasoning, False Cause & Limited Choice

2. Logical Fallacies: Hasty Generalization, Circular Reasoning, False Cause & Limited Choice

Watch this video lesson to see how you can identify cases where logic is not sound. Learn the characteristic traits of hasty generalization, circular reasoning, false cause, and limited choice.

Logical Math Connectors: Conjunctions and Disjunctions

3. Logical Math Connectors: Conjunctions and Disjunctions

Watch this video lesson to learn how to identify conjunctions and disjunctions. Also learn the connectors that are used with each. Learn how you can use them to make statements.

Conditional Statements in Math

4. Conditional Statements in Math

Sometimes, what is true in the mathematical world of logic is false in the real world. Check out this lesson to learn how to identify conditional statements and how you can differentiate between what is logically true and what is true in reality.

The Parallel Postulate: Definition & Examples

5. The Parallel Postulate: Definition & Examples

In this lesson, you will learn about an important postulate in Euclidean geometry, called the Parallel Postulate. It sounds kind of hard, but this lesson explains it in simple terms and provides several examples of it as well.

Programming Logic & Syntax: The Programming Toolbox

6. Programming Logic & Syntax: The Programming Toolbox

A programming language has its own syntax that dictates how words and symbols can be put together to form a program. Learn about programming's use of statements, variables and keywords in this video lesson.

Boolean Logic, Operators & Expressions

7. Boolean Logic, Operators & Expressions

Programming uses Booleans, which are used to represent values of true and false. Many operations use Boolean logic. Learn how Boolean operators and expressions are used.
