Ch 39: NMTA Middle Grades Math: Symmetry, Similarity & Congruence

About This Chapter

The NMTA Middle Grades Mathematics test has been replaced by the National Evaluation Series Middle Grades Mathematics test in New Mexico. Watch comprehensive video lessons to get reacquainted with symmetry, similarity and congruence as you prepare to take the NES Middle Grades Mathematics test.

NMTA Middle Grades Math: Symmetry, Similarity & Congruence - Chapter Summary

As you get ready to take the NES Middle Grades Mathematics test, it's important that you brush up on your knowledge of symmetry, similarity and congruence. The video lessons in this chapter can help you accomplish that goal by refreshing your memory on the methods necessary to answer questions that address the following on the test:

  • Defining the line of symmetry in geometric shapes
  • Determining if shapes like triangles, squares and rectangles are congruent
  • Understanding what it means to have similarity in geometric shapes
  • Identifying parallel lines in geometric shapes
  • Getting the gist of parallel, perpendicular and transverse lines
  • Constructing perpendicular lines in geometry
  • Identifying perpendicular lines in geometric shapes.

The skilled instructors who present the video lessons offer the comprehensive guidance you need to make your test preparation simple. The videos are easy to follow and offer transcripts that allow you to read any parts you want to review.

Objectives of the NMTA Middle Grades Math: Symmetry, Similarity & Congruence Chapter

The NES Middle Grades Mathematics test is designed to assess your comprehension of this subject area to make sure you're ready to teach in the classroom and secure your teaching license in New Mexico. NMTA Middle Grades Math: Symmetry, Similarity & Congruence chapter topics are found in the measurement and geometry portion of the test, which constitutes about 25% of the total exam. By watching the video lessons in this chapter, you gain greater insight into the topic, which ensures you'll be prepared to tackle this portion of the exam. Self-assessment quizzes are also available to help you practice answering questions formatted similarly to those found on the exam.

All of the questions on the test are multiple choice, typically take the form of short paragraphs, sentences or questions, and may be accompanied by illustrations, diagrams or graphs. Following each question is a set of four answers, one of which you will be asked to select as the best option.

What is a Line of Symmetry in Geometric Shapes?

1. 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.

Congruence in Geometric Shapes

2. Congruence in Geometric Shapes

Watch this video lesson to learn how you can determine whether two shapes are congruent or not. You will learn what the one criterion is when determining congruency between two shapes.

Similarity in Geometric Shapes

3. Similarity in Geometric Shapes

View this lesson to learn how you can determine whether shapes are similar. Find out how to use the one rule that tells you when your two shapes are geometrically similar.

Parallel, Perpendicular and Transverse Lines

4. 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.

Identifying Parallel Lines in Geometric Shapes

5. 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.

Constructing Perpendicular Lines in Geometry

6. Constructing Perpendicular Lines in Geometry

In this video lesson, you will see how to use geometric construction to draw perpendicular lines. Learn why geometric construction is useful. Also find out the only two tools in addition to your pencil that you need to do this.

Identifying Perpendicular Lines in Geometric Shapes

7. 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.
