MTEL Mathematics (Elementary): Circles & Circular Arcs - Chapter Summary

In this chapter, our instructors break down principles dealing with circles and circular arcs. After working through the lessons, you will be prepared to answer questions on the exam relating to:

  • Properties of shapes
  • Circular arcs and circles
  • Central and inscribed angles
  • Measure of an arc
  • Tangent of a circle
  • Segment of a circle

Reviewing circle-related topics won't be problematic if you use this chapter as a study guide. In it are all kinds of interactive resources, such as video lessons and transcripts. Use the self-assessment quizzes to check your knowledge, seeing if there are any areas you need to improve on before taking the real exam.

Properties of Shapes: Circles

1. Properties of Shapes: Circles

Circles are fundamental to everything we do. But, did you know they're much more than just round shapes? In this lesson, we'll look at the various parts of circles and how they all relate.

Circles: Area and Circumference

2. Circles: Area and Circumference

Understanding how to calculate the area and circumference of circles plays a vital role in some of our everyday functions. They serve as the foundation for operating with three-dimensional figures. Learn more about the area and circumference of circles in this lesson.

Circular Arcs and Circles: Definitions and Examples

3. 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

4. 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

5. 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.

Tangent of a Circle: Definition & Theorems

6. 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

7. 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.

Segment of a Circle: Definition & Formula

8. Segment of a Circle: Definition & Formula

A circle is an important geometric shape in our world and is very relevant to our everyday experiences. In this lesson, we will explore one aspect of the circle, the segment. In addition, we will also discuss a few other vocabulary words related to the circle.
