- Line segments and rays
- Points, lines and angles
- Geometric constructions
- Line segment bisection
- The midpoint theorem
- Types of angles
- Angle bisectors

Take advantage of this chapter's entertaining videos, transcripts and multiple-choice quizzes to prepare for your teacher licensing exam. Each of these resources features expert instruction and a self-paced format to help you focus on the important geometry topics you need to review.

### OAE Middle Grades Math: Properties of Lines Chapter Objectives

The OAE Middle Grades Math content area exam is used to assess the qualifications of prospective middle school math teachers in Ohio. This standardized test includes 150 multiple-choice questions assessing your knowledge of four content domains.

Answers to questions found in the measurement and geometry content domain will account for 25% of your test score. You can prepare for geometry questions focusing on the properties of points, lines and angles by utilizing this chapter's video lessons and quizzes.

### 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. 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.

### 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.

### 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.

### 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.

### 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.

### 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.

### 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.

### 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.

### 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.
