# Ch 26: FTCE Middle Grades Math: Lines & Angles

### About This Chapter

## FTCE Middle Grades Math: Lines & Angles - Chapter Summary

Watch these video lessons to reinforce your understanding of important material on angles and lines. This chapter will leave you well-prepared for any Florida Teacher Certification Examinations (FTCE) Middle Grades Mathematics exam questions on the following:

- Properties of line segments and rays
- Transverse, parallel and perpendicular lines
- Definitions for right, acute and obtuse angles
- Complementary and supplementary angles
- Vertical, alternate interior and corresponding angles
- Adjacent and congruent angles

In addition to watching these video lessons, you can read the lesson transcripts to improve your retention of the material. Then take the lesson quizzes to discover any topics you don't fully understand. To improve your understanding of those topics, use the video tags to return to and study the parts of the lessons that explained them.

### 1. Line Segments & Rays: Definition & Measurement

Watch this video lesson to learn the difference between a line segment and a ray. You will also learn how to measure and add line segments. Learn why you can't measure or add a ray.

### 2. Parallel, Perpendicular and Transverse Lines

What are the different types of lines? Where are they visible in the real world and how can you recognize them? Find out here and test your knowledge with a quiz.

### 3. Constructing a Parallel Line Using a Point Not on the Given Line

Watch this video lesson, and you will learn how to draw parallel lines with just a compass and a straightedge. Also, learn why you would want to be able to do this in real life.

### 4. Graphs of Parallel and Perpendicular Lines in Linear Equations

When we deal with linear equations, we sometimes come across equations that are parallel to each other or perpendicular to each other. You will see what they look like when graphed in this video lesson.

### 5. What is a Right Angle? - Definition & Formula

In this lesson, you will learn about the properties that identify right angles. You will also discover where right angles can be found and learn about what makes them so useful. You can then test your knowledge with a quiz.

### 6. What is an Acute Angle? - Definition, Description & Examples

In this lesson, you'll learn what makes an angle acute and see a few different examples of them. After the lesson, you can test your new knowledge with a brief quiz.

### 7. What is an Obtuse Angle? - Definition & Examples

In this lesson, you'll learn what angles, right angles, and obtuse angles are; you'll see a few examples of different obtuse angles. Test your knowledge with a brief quiz once you've completed the lesson.

### 8. Complementary Angles: Definition, Theorem & Examples

In this lesson, we will define complementary angles and see how they may appear in diagrams. We will discuss two common theorems that involve complementary angles. Then you can test your knowledge with a quiz.

### 9. Supplementary Angle: Definition & Theorem

There are many important angle pairs in geometry. In this lesson, we'll learn about supplementary angles, including what they are, where they are used, and why you need to know about them.

### 10. Types of Angles: Vertical, Corresponding, Alternate Interior & Others

In addition to basic right, acute, or obtuse angles, there are many other types of angles or angle relationships. In this lesson, we will learn to identify these angle relationships and discuss their measurements.

### 11. What Are Adjacent Angles? - Definition & Examples

In this lesson, you will learn how to identify whether angles are adjacent. After looking at several examples, you will be able to test your knowledge with a quiz.

### 12. Congruent Angles: Definition & Examples

In this lesson, we'll explore the definition of a congruent angle. You'll learn how to draw a congruent angle, explore examples of congruent angles, and test your knowledge with a short quiz.
