Ch 37: NMTA Math: Parallel Lines & Polygons

About This Chapter

This chapter presents a series of short, entertaining videos to demonstrate the parallel lines and polygons topics you can expect to be tested on while taking the NMTA Math certification exam. If you have any questions about parallel lines, polygons, or basic geometry, ask our instructors for help.

NMTA Math: Parallel Lines & Polygons - Chapter Summary

Watch these quick, appealing videos to get reacquainted with the parallel lines and polygons concepts you'll be asked about on the NMTA Math exam. You'll see illustrations and explanations of the concepts likely to appear on the certification assessment, such as:

  • Transversal angles
  • Parallel line proofs
  • The Parallel Postulate
  • Regular polygons
  • Finding polygon diagonals
  • Calculating perimeter and area
  • Angle measurements

To ensure you retain the information from the videos, be sure to take the lesson quizzes so you can practice the proofs and measurement methods you've studied. Refer to the video transcripts to quickly hunt down the most important concepts, which are highlighted.

Objectives of the NMTA Math: Parallel Lines & Polygons Chapter

Geometry and measurement questions make up nineteen percent of the NMTA Math assessment. Get ready for these questions by working through the parallel lines and polygons lessons in this chapter. Use the lesson quizzes to practice for the exam. They mimic format of the questions on the computer-administered NMTA so you can get comfortable with the testing style and conditions.

The remainder of the exam covers the following four content areas: calculus and trig; math processes and number sense; stats, probability and discrete math; and patterns, algebra and functions. The exam is timed - you'll be given four hours and fifteen minutes to complete it.

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.
