# Ch 28: Praxis Mathematics: Polygons

### About This Chapter

## Praxis Mathematics: Polygons - Chapter Summary

In this chapter, the lessons will show you how to compute and reason about perimeter in two dimensions. You'll learn to calculate the perimeters of various types of polygons and to solve problems using the properties of polygons. These videos cover the following topics that will help prepare you for these types of questions on the exam:

- Determining the perimeters of quadrilaterals and irregular or combined shapes
- Determining the perimeters of triangles and rectangles
- Using the properties of polygons to help solve problems

You will be guided through the videos by experienced instructors who know how to make the lessons informative and entertaining. You will enjoy your preparation for the exam as you learn about polygons and their properties.

### Objectives of the Praxis Mathematics Course

Individuals who want to teach math at the secondary school level must pass the Praxis Mathematics exam in many states. The exam has 50 multiple-choice questions, and you will be allotted 2 hours to finish the entire test. The questions on polygons and their properties are part of the test's section on geometry. The geometry section consists of 5 questions, which equals 10% of the entire exam.

The questions on the Praxis Mathematics test present you with a problem and four options for answers. The self-assessment quizzes at the end of the video lessons will allow you to check your knowledge of the subject and become familiar with the test format.

### 1. Regular Polygons: Definition & Parts

What makes a polygon a polygon? And what shapes are considered polygons? In this lesson, find out the answers to these questions and more as we learn all about polygons and their parts.

### 2. Finding the Perimeter of Polygons

In this video lesson, you will learn the process you need to take to find the perimeter of polygons. You will also learn that there is a shortcut if your polygon is a regular polygon.

### 3. Similar Polygons: Definition and Examples

Watch this video to learn what makes two polygons similar to each other. You'll also learn the one distinguishing aspect of similar polygons and see an example of how to compare two polygons.
