### About This Chapter

## HiSET Mathematics: Quadrilaterals - Chapter Summary

You'll be ready for any related content on the HiSET Mathematics subtest after seeing the numerous definitions, properties and formulas dealing with quadrilaterals in this chapter. Some particular focus areas in this chapter's lessons include the following:

- Complex figures
- Measuring the area of a rhombus
- Area of a parallelogram
- Properties of squares, rectangles and trapezoids

The combination of text transcripts and video lessons gives you thorough coverage of the formulas in order to maximize your understanding. You can go back and forth within any video lesson with ease using the video tags according to how much review you want.

### Objectives of the HiSET Mathematics: Quadrilaterals Chapter

The HiSET Mathematics subtest has 50 questions and they are all multiple-choice. The 90-minute subtest assesses your familiarity with a variety of subject matter, including quadrilaterals, as a component to your earning a high school equivalency credential. The multiple-choice quizzes in this chapter give you practice with the material and let you see roughly how some of your test questions may be written. Calculators are permitted on the whole subtest, in case you'd like to use one.

### 1. Parallelograms: Definition, Properties, and Proof Theorems

Watch this video lesson to learn how you can identify parallelograms. You will see the unique properties that belong to the parallelogram. You will see the special side and angle characteristics needed to prove a certain shape is a parallelogram.

### 2. Measuring the Area of a Parallelogram: Formula & Examples

Watch this video lesson to learn the simple formula to find the area of a parallelogram. Learn what measurements you need, how to label your parallelogram, and how to use the formula.

### 3. Measuring the Area of a Rhombus: Formula & Examples

Did you know that there are three ways to find the area of a rhombus? Watch this video lesson to learn all three of them. See what information you need for each method as well as the steps required for each.

### 4. Rectangles: Definition, Properties & Construction

Watch this video lesson to learn a bit about rectangles. Learn why rectangles are the building blocks of many homes. Also, learn about the properties that make a rectangle unique from other shapes. Finally, learn how you can draw one.

### 5. Measuring the Area of a Rectangle: Formula & Examples

Look around you, and you see rectangles all over the place. And if you see paint, carpet, or anything that covers a rectangular area, you can be sure that someone has measured the area of the rectangle. Watch this video lesson to learn more.

### 6. Squares: Definition and Properties

Squares can be found in many places in the real world. Watch this video lesson to see how useful they can be and also to learn how to find the perimeter and area of a square.

### 7. Trapezoids: Definition and Properties

Watch this video lesson to learn what a trapezoid has to do with a triangle. Also, learn the special words that describe the various parts of a trapezoid. You will also see special types of trapezoids.

### 8. Measuring the Area of a Trapezoid

In this video lesson, you will watch and learn how you can find the area of trapezoid. Learn what measurements you need to have on hand as well as the formula that you need to use.

### 9. Area of Complex Figures

Finding the area of shapes isn't always as simple as it is with squares and rectangles. In this lesson, you'll learn how to find the area of complex figures. This includes finding the area of unusual shapes and finding the area of parts of shapes.
