  • Defining circular arcs and circles
  • Measuring an arc
  • Finding the measure of an inscribed angle
  • Examining the tangent of a circle
  • Analyzing measurements of angles and lengths involving tangents, chords and secants
  • Identifying inscribed and circumscribed figures
  • Constructing inscribed and circumscribed triangles

The video lessons are designed to provide you with step-by-step guidance to ensure you fully understand circular arcs and measurements. Presented in a visually entertaining package, the videos also make the learning process fun.

OAE Middle Grades Math: Circular Arcs & Measurement Chapter Objectives

The OAE Middle Grades Mathematics assessment tests your comprehension of the subject to make sure you're ready to teach it in the middle school classroom. It also determines your readiness to secure a subject-specific teaching license in the state of Ohio. The topics in this OAE Middle Grades Math: Circular Arcs & Measurement chapter are located in the measurement and geometry section of the test, which constitutes 25% of the total exam. Use the video lessons to refresh your knowledge of circular arcs and measurement and read accessible video transcripts to further review the materials. You can also take self-assessment quizzes to strengthen your knowledge of this subject and prepare for the types of questions you will encounter on exam day.

All of the questions on the assessment are multiple choice and based on specific test competencies. The questions might be accompanied by a graph, diagram or illustration to help you conceptualize an idea and solve a problem. Following each question is a set of four answers, one of which you will be required to choose as the best option.

9 Lessons in Chapter 47: OAE Middle Grades Math: Circular Arcs & Measurement
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.

Regular Polygons: Definition & Parts

8. 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

9. 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.
