Ch 18: Compass Math: Basic Geometry

About This Chapter

These quick, engaging videos demonstrate the basic geometry concepts you'd do well to review for your Compass Math placement assessment. Each lesson comes with a thorough transcript that highlights the important ideas.

Compass Math: Basic Geometry - Chapter Summary

Take your Compass assessment preparation on the go with these short, convenient, mobile device-accessible video lessons. As you work through this chapter, you'll refresh your memory of important basic geometry concepts like:

  • Inductive reasoning and deductive reasoning
  • Important geometric postulates and figures
  • Applying the laws of algebra to geometry
  • Direct proofs and geometric proofs

Each lesson is followed by a short multiple-choice self-assessment so you can practice using basic geometry and pinpoint concepts that need additional review. Be sure to reach out to our instructors any time you need help.

Objectives of the Compass Math: Basic Geometry Chapter

This chapter is loaded with great tools that help you remember and practice the basic geometry you'll see on your Compass Math course placement assessment. Your results will be used by your school to select an appropriate math class, so it's important to review the concepts you already know so you don't get stuck in a class below your level.

Questions on the Compass Math assessment are in multiple-choice format and meted out by a computer, which adjusts the difficulty levels of the questions it asks as you work through the test. There is no time limit for the assessment.

What is Geometry?

1. What is Geometry?

Geometry can be traced all the way back to 2000 BC. Watch this video lesson and learn how much geometry has grown over time, and how people from Egypt, Greece, and France have contributed to the geometry we now use today.

Inductive & Deductive Reasoning in Geometry: Definition & Uses

2. Inductive & Deductive Reasoning in Geometry: Definition & Uses

Watch this video lesson, and you will learn how important inductive and deductive reasoning is in the field of mathematics, especially when dealing with proofs in geometry. Learn how these two fundamental forms of reasoning give rise to formal theorems.

Properties and Postulates of Geometric Figures

3. Properties and Postulates of Geometric Figures

In geometry, there are some basic postulates that are relied upon as the basis for other theorems. Watch this video to learn about the postulates that deal with points, lines, and planes.

Algebraic Laws and Geometric Postulates

4. Algebraic Laws and Geometric Postulates

Watch this video to learn about the basic algebraic laws that are also part of the basic geometric postulates that form the basis for the geometry that we know and study today.

Direct Proofs: Definition and Applications

5. Direct Proofs: Definition and Applications

In math, we can't explain that something is true just because. That's not enough. In this lesson, we'll learn to prove things using one of our most straightforward tools, the direct proof.

Geometric Proofs: Definition and Format

6. Geometric Proofs: Definition and Format

Do you have something to prove? Can you explain why? In this lesson, we'll learn all about geometric proofs, including the parts that comprise a proof.
