Ch 48: NES Middle Grades Math: Circular Arcs & Measurement

About This Chapter

In this chapter, you will get a refresher in arcs and circles as well as measuring various types of angles and lengths. Practice for the NES Middle Grades Mathematics exam by taking the chapter test and lesson quizzes.

NES Middle Grades Math: Circular Arcs & Measurement - Chapter Summary

As you look toward the National Evaluation Series (NES) Middle Grades Mathematics exam, brush up on your measurement skills and improve your understanding of how to work with circles and arcs. Our experienced instructors will help you meet your licensure goals with expert instruction and good-humored examples. This chapter brings you a review of such topics with entertaining videos explaining how to:

  • Measure an arc
  • Measure inscribed angles
  • Measure lengths and angles which involve tangents
  • Work with chords, secants and tangents
  • Construct circumscribed and inscribed triangles and other figures
  • Identify regular polygons
  • Identify a sector's arc length

Every video is accompanied by a comprehensive study suite which includes printable study materials, self-assessments, and a thorough quiz review process. Navigation is simple with a sidebar lesson selection list and in-video topic tags. The videos are brief enough to fit just about anywhere in your busy schedule, and they are entirely web-based and viewable on your mobile device.

NES Middle Grades Math: Circular Arcs & Measurement Chapter Objectives

You will be given 4 hours and 15 minutes to complete the 150 multiple-choice questions on the NES Middle Grades Mathematics exam. It contains four content domains, and the Measurement and Geometry domain represents 25% of the overall content. Within this domain is Objective 0008, which deals with Euclidean geometry. This is where this chapter's content would fall.

Scoring is done on a scaled system from 100-300, with the national benchmark score of 220 needed to pass the exam. The test administrators will score your exam before you leave the center, providing your scaled score immediately. For your detailed score report, however, you will have to wait a couple of weeks; they publish online according to a schedule maintained on the NES website. Also head over to their website to register for the test, look up testing locations and dates, and download a complete breakdown of the exam.

Circular Arcs and Circles: Definitions and Examples

1. 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.

Measure of an Arc: Process & Practice

2. 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

3. 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

4. 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

5. 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

6. 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.

Inscribed and Circumscribed Figures: Definition & Construction

7. 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.

Constructing Inscribed & Circumscribed Triangles

8. Constructing Inscribed & Circumscribed Triangles

View this lesson to learn how you can construct inscribed and circumscribed triangles. Learn how both involve circles. All you need are a ruler and a compass.

Regular Polygons: Definition & Parts

9. Regular Polygons: Definition & Parts

What makes a polygon a polygon? And what shapes are considered polygons? In this lesson, find out the answers to these questions and more as we learn all about polygons and their parts.

Arc Length of a Sector: Definition and Area

10. Arc Length of a Sector: Definition and Area

In this lesson, we'll slice up a circle like it's a pizza and learn how to find out useful information about our slices. We'll find out the area of these sectors, or pie slices. We'll also learn about arc lengths.
