Ch 30: Praxis Mathematics: Circles

About This Chapter

Get ready for the Praxis Mathematics test with this chapter on circles. Instructors discuss tangent theorems and the properties of chords, secants and arcs to get you ready for the exam's geometry questions.

Praxis Mathematics: Circles - Chapter Summary

Let our instructors demonstrate the uses of theorems and circle properties to calculate measurements for chords, secants, arcs and angles inscribed within a circle. Instructional videos on the following topics can get you ready for geometry questions appearing on the Praxis Mathematics exam:

  • Properties of circles, tangents, chords and secants
  • Methods for constructing inscribed and circumscribed figures
  • Processes for measuring arcs, angles and lengths
  • Uses of tangent theorems

These test prep materials can be used to review geometry topics you're comfortable discussing or develop a better understanding of areas you're not quite familiar with. Short, entertaining video lessons are supplemented by matching transcripts and self-assessment quizzes you can use to get feedback on your progress.

Praxis Mathematics: Circles Objectives

This chapter's video lessons have been assembled to help you study chords, inscribed angles, tangents and arcs, so you can answer Praxis Mathematics exam questions requiring a knowledge of circle properties and their relation to other geometric figures.

Around five of the exam's 50 multiple-choice questions cover these types of geometry topics. Other content domains address such areas as number theory, calculus, probability and discrete mathematics. Passing scores vary by state, though test results are generally used to award teaching credentials to aspiring secondary school math teachers.

Properties of Shapes: Circles

1. Properties of Shapes: Circles

Circles are fundamental to everything we do. But, did you know they're much more than just round shapes? In this lesson, we'll look at the various parts of circles and how they all relate.

Inscribed and Circumscribed Figures: Definition & Construction

2. Inscribed and Circumscribed Figures: Definition & Construction

A square and a circle may be different shapes, but they still can have a unique relationship. In this lesson, we'll learn about inscribed and circumscribed figures.

Measure of an Arc: Process & Practice

3. Measure of an Arc: Process & Practice

What is the measure of an arc? And what is the difference between a minor arc and a major arc? Find out all that and practice finding the measure of an arc in this lesson.

How to Find the Measure of an Inscribed Angle

4. How to Find the Measure of an Inscribed Angle

Finding the measure of an inscribed angle requires knowing a little information. In this lesson, we'll find the measure of an inscribed angle when we know the measure of the central angle or one or more of the arcs formed by the angle.

Tangent of a Circle: Definition & Theorems

5. Tangent of a Circle: Definition & Theorems

What happens when a line just barely touches a circle? It's a tangent! In this lesson, we'll learn all about tangents to circles, including a few key theorems. We'll also look at tangent circles.

Measurements of Angles Involving Tangents, Chords & Secants

6. Measurements of Angles Involving Tangents, Chords & Secants

When lines and circles meet, angles are formed. Fortunately, we can determine the measure of these angles, whether they're formed by tangents, secants or chords, just by knowing the measure of the created arcs.

Measurements of Lengths Involving Tangents, Chords and Secants

7. Measurements of Lengths Involving Tangents, Chords and Secants

The lengths of chords, tangents and secants take on unique relationships when they're drawn on circles. In this lesson, we'll define those relationships and see them in action.

Circular Arcs and Circles: Definitions and Examples

8. Circular Arcs and Circles: Definitions and Examples

What is a circle? In this lesson, find out all about the circle and its many parts, including circular arcs and semicircles. Also, discover how a locus works in creating a circle, parallel lines and more.
