### About This Chapter

## TABE Math - Grade 4: Geometry - Chapter Summary

Use the lessons in this chapter to acquire skills needed to correctly answer geometry questions when taking the TABE exam. They'll provide you with an idea of what concepts are covered on the exam. By working through these lessons, you can review:

- Angles, lines and points
- Acute, obtuse and right angles
- Definition of line segment and rays
- Properties and definition of a triangle
- Line of symmetry in geometric shapes
- Defining and identifying perpendicular, parallel and transverse lines
- Classifying triangles

Our lessons can be used to review geometric equations that you will possibly see on the exam. Complete with quizzes and detailed transcripts, these lessons can help you effectively remember information. Ask questions of the instructors when you visit the Dashboard to be sure you understand the geometric shapes and formulas you'll find on the exam.

### 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. 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.

### 4. 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.

### 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. 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.

### 7. Identifying Parallel Lines in Geometric Shapes

Watch this video lesson to learn how you can spot parallel lines in a rectangle, in a square, and in a parallelogram. You will learn how many pairs of parallel lines each of these shapes has.

### 8. Identifying Perpendicular Lines in Geometric Shapes

Do you know what a perpendicular line is? Do you know how to spot one in a geometric shape? This lesson will tell you how to spot perpendicular lines in squares, rectangles, triangles, and trapezoids.

### 9. Triangles: Definition and Properties

What makes a shape a triangle? In this lesson, we'll explore the definition of a triangle, then analyze the parts of triangles, including the vertices, base and height.

### 10. Classifying Triangles by Angles and Sides

Not all triangles are the same. There are equilateral, isosceles and scalene triangles. Then there are right, acute and obtuse triangles. In this lesson, we'll learn how to classify triangles using their sides and angles.

### 11. What is a Line of Symmetry in Geometric Shapes?

After viewing this lesson, you should be able to identify shapes that have a line of symmetry in them and know how to find where this line is. A short quiz to test your knowledge will follow the lesson.
