Ch 40: MEGA Middle School Math: Properties of Lines

About This Chapter

These lessons and assessments will help you prepare for questions on the MEGA Middle School Math exam about the different types and properties of lines and angles.

MEGA Middle School Math: Properties of Lines - Chapter Summary

Watch these lesson videos to prepare for questions on the MEGA Middle School Math exam related to the methods used to identify the properties of lines, line segments, rays and angles. In these lessons our expert instructors will also talk about the techniques used to construct lines, angles and other geometric figures. After this chapter you should have a better understanding of:

  • Measurements of line segments and rays
  • Uses of lines and angles when constructing geometric figures
  • Midpoint theorem and line segment bisection
  • How to divide line segments into equal parts
  • Different types of angels
  • How to construct an angle bisector

After watching these lesson videos, read over the lesson transcripts for written overviews of the material. Once you've completed a lesson, take the lesson quiz that accompanies it to test your understanding of the information presented. Using your quiz results, identify any material you don't understand and then return to the respective segments using the video tags for further review.

Line Segments & Rays: Definition & Measurement

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.

Points, Lines & Angles in Geometry

2. Points, Lines & Angles in Geometry

After watching this video lesson, you should understand the basic terms that form the foundation of geometry. Learn what a point is, what a line is, what an angle is, and learn about a special type of angle called a right angle.

Geometric Constructions Using Lines and Angles

3. Geometric Constructions Using Lines and Angles

Watch this video lesson to learn about geometric construction and how you can copy line segments and angles without using any numbers. All you need is a straight edge and a compass.

Practice Making Geometric Constructions with Tools

4. Practice Making Geometric Constructions with Tools

There are a number of tools available to geometry students to help make their work a bit easier. In this lesson, we will review how to use many of them in order for you to get the most out of every geometry class.

Line Segment Bisection & Midpoint Theorem: Geometric Construction

5. Line Segment Bisection & Midpoint Theorem: Geometric Construction

Watch this video lesson and you will learn how to bisect a line segment without measurements using just a compass and a straight edge. You'll also learn about the midpoint theorem, which lets you calculate the midpoint if you have the measurements.

Dividing Line Segments into Equal Parts: Geometric Construction

6. Dividing Line Segments into Equal Parts: Geometric Construction

Watch this video lesson to learn one way to easily divide any line segment into as many equal parts as you need. Also, learn where in real life this skill comes in handy.

Types of Angles: Vertical, Corresponding, Alternate Interior & Others

7. 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.

Complementary, Supplementary, Vertical & Adjacent Angles

8. Complementary, Supplementary, Vertical & Adjacent Angles

After watching this video lesson, you will know how to locate complementary, supplementary, vertical, and adjacent angles. You will understand how easy it is to visually see them. You will also know what to look for.

Constructing an Angle Bisector in Geometry

9. Constructing an Angle Bisector in Geometry

Watch this video lesson to learn a cool way to split an angle in half. You can use this method to split a pie slice in half where you can be sure each side is equal.

Constructing Equilateral Triangles, Squares, and Regular Hexagons Inscribed in Circles

10. Constructing Equilateral Triangles, Squares, and Regular Hexagons Inscribed in Circles

Constructing an accurate triangle, square, or hexagon within a circle is a matter of a few simple steps, and can be extremely practical. In this lesson, we'll practice the construction of those three shapes.
