Objectives of the GACE Math: Parallel Lines & Polygons Chapter

The assessments offered by GACE evaluate aspiring teachers' professional competencies in different academic areas. They are designed to certify educators and verify their qualifications to teach. This chapter on parallel lines and polygons is one aspect of the GACE test in mathematics. The multiple-choice quizzes that you will find at the end of each of this chapter's lessons will show you questions similar to those found on the test itself.

The GACE Math exam consists of two subtests, offered separately or in a combined format. Both subtests contain 45 selected-response questions and will last for approximately 4-5 hours. GACE offers test-takers the option to purchase a specially designed practice exam prior to taking the actual test.

Angles Formed by a Transversal

1. Angles Formed by a Transversal

When you have a pair of parallel lines and a transversal, something very interesting happens to the angles that are formed. You can see this happen in real life at street intersections and such. Watch this video lesson to learn about all of this.

Parallel Lines: How to Prove Lines Are Parallel

2. Parallel Lines: How to Prove Lines Are Parallel

Watch this video lesson to learn how you can prove that two lines are parallel just by matching up pairs of angles. Learn which angles to pair up and what to look for.

Using Converse Statements to Prove Lines Are Parallel

3. Using Converse Statements to Prove Lines Are Parallel

Because a pair of parallel lines produces unique angle characteristics, we can use this information to our advantage. Watch this video lesson to see how we turn this advantage into converse statements to help us prove parallel lines.

The Parallel Postulate: Definition & Examples

4. The Parallel Postulate: Definition & Examples

In this lesson, you will learn about an important postulate in Euclidean geometry, called the Parallel Postulate. It sounds kind of hard, but this lesson explains it in simple terms and provides several examples of it as well.

Regular Polygons: Definition & Parts

5. 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.

How to Find the Number of Diagonals in a Polygon

6. How to Find the Number of Diagonals in a Polygon

At first, you might think that the diagonals of a polygon are pretty useless, but watch this video lesson to learn how diagonals are used in real life. You will learn the formula to find how many diagonals a polygon has as well as how to use it.

Finding the Perimeter of Polygons

7. 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.

Measuring the Area of Regular Polygons: Formula & Examples

8. Measuring the Area of Regular Polygons: Formula & Examples

Watch this video lesson to learn why a regular polygon makes your life easier when it comes to finding the area inside one. Learn the one formula for area that will work for any type of regular polygon.

How to Measure the Angles of a Polygon & Find the Sum

9. How to Measure the Angles of a Polygon & Find the Sum

Watch this video lesson to learn the one formula that lets you find the measure of angles in any regular polygon. Also, learn how you can tell if you are working with a regular polygon or not.
