About This Chapter

Simplify the process of studying for the MTEL Mathematics assessment by reviewing the short videos in this chapter. Get reacquainted with circular arcs and measurement, then gauge your comprehension with self-assessment quizzes.

MTEL Math: Circular Arcs & Measurement - Chapter Summary

The lessons in this chapter make it easier for you to answer questions related to circular arcs and measurement on the MTEL Mathematics assessment. Review the videos, and you will be ready for the following on exam day:

  • Defining circular arcs and circles
  • Explaining the measure of an arc and calculating the measure of an inscribed angle
  • Providing the meaning and theorems of the tangent of a circle
  • Measuring the angles and lengths of tangents, chords and secants
  • Creating inscribed and circumscribed figures and triangles
  • Identifying parts of regular polygons
  • Finding the area of the arc length of a sector

You can easily navigate the video lessons, and choose those you want to watch in any sequence that works best for you. Take advantage of timelines that allow you to identify and skip to key topics within the videos without watching them in their entirety.

MTEL Math: Circular Arcs & Measurement Chapter Objectives

The topics in this chapter on circular arcs and measurement prepare you for questions in the geometry and measurement subarea of the MTEL Mathematics assessment. This subarea is found in the multiple-choice portion and constitutes about 19% of the total test. In addition to reviewing the lessons in this chapter, you can assess your readiness to take the exam by taking short lesson quizzes and a practice chapter exam. If you have any questions about lesson topics, don't hesitate to submit them to our experts.

The assessment is a subject-matter test that is taken on computer and lasts four hours. It consists of 100 multiple-choice questions and two open-response assignments. The goal of the test is to ensure educators in Massachusetts are qualified for the licensure they need to teach mathematics in classrooms. To pass, you must earn a minimum score of 240.

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.
