Ch 39: MTLE Mathematics: Circles & Arc of a Circle

About This Chapter

The Circles & Arc of a Circle chapter in our MTLE Mathematics preparation course and study guide will teach you what you need to know about circles and circle arcs. Use our short video lessons and quizzes to help you prepare for the MTLE Math exam.

MTLE Mathematics: Circles & Arc of a Circle

In this chapter, we'll be taking a look circles and circle arcs and then exploring some effective techniques for calculating arc length and measuring inscribed angles. Your knowledge can be applied when you're taking the MTLE Mathematics exam. In our Circles & Arc of a Circle chapter, you'll learn about:

  • Definition of circular arcs and circles
  • Central and inscribed angles
  • Measuring an arc
  • Calculating the measure of an inscribed angle
  • Tangents of circles and related theorems
  • Measurements of lengths and angles
  • Arc length of a sector
  • Calculating arc length and measure

We can show you effective techniques and explain circle concepts in a clear, concise format that's specially tailored to the MTLE Mathematics test. With our expert-narrated video lessons and our self-assessment quizzes, you'll be able to learn at your own pace and focus on the areas you need the most help with.

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.

Central and Inscribed Angles: Definitions and Examples

2. Central and Inscribed Angles: Definitions and Examples

When we're working with circles, there are two key angles to know: central angles and inscribed angles. These angles have a few special theorems, which we'll discuss and practice using in this lesson.

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.

Arc Length of a Sector: Definition and Area

8. 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.

Arc Length: Definition & Equation

9. Arc Length: Definition & Equation

Arc length is an important aspect to understanding portions of curved lengths. As you will learn in this lesson, combining our knowledge of circumference and central angle measures allows us to find arc length.

Arc Measure: Definition & Formula

10. Arc Measure: Definition & Formula

Arc measure is a way of identifying an arc. In this lesson, we'll learn how to define and calculate arc measure while discussing the different elements involved in this calculation.
