## OAE Mathematics: Circles & Arc of a Circle - Chapter Summary

As part of your review for the Ohio Assessments for Educators (OAE) Mathematics exam, watch the videos in this chapter to review what you need to know about circles and the arcs of a circle. These videos are taught by expert instructors who explain the components and measurements of circles and circular arcs so you are prepared to answer test questions related to:

• Equations used to find the area and circumference of circles
• Central and inscribed angles
• Processes used to measure arcs
• Theorems of tangents of a circle
• Finding measurements of angles and lengths involving tangents
• Finding the area of an arc length of a sector

In the event you become confused about a topic covered in this chapter, be sure to ask our instructors any questions you may have. You can also reinforce your understanding of the information presented by completing lesson quizzes or the chapter exam. If you feel you could still benefit from an alternative review of the material, try reading over the lesson transcripts that give an overview of the information in a written format.

### OAE Mathematics: Circles & Arc of a Circle Chapter Objectives

The OAE Mathematics test is a teachers certification exam used in the state of Ohio to measure educators' mastery over mathematics. As a test taker, you will complete 150 multiple-choice questions in a four-hour and 15-minute testing session. Of the material you will see on this computerized exam, 19% of the questions belong to the domain of Measurements and Geometry and another 19% are part of the Trigonometry and Calculus domain. Both of these domains could include questions asking about circles and circular arcs. By completing this chapter you will gain a better understanding of the components, theorems and measurements of circles used when answering such questions.
