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

This chapter will help you get ready for the National Evaluation Series (NES) Middle Grades Mathematics exam by explaining how to identify, construct, and analyze similar/congruent shapes and lines. You will be treated to entertaining and insightful videos from our talented instructors with lessons on such topics as:

• Lines of symmetry
• Congruence and similarity in geometric shapes
• Parallel, transverse, and perpendicular lines

These video-based lessons create a single point of study for your exam preparation: there is no need to bounce among several study resources to review and practice your math skills. Watch the videos, then review the lesson transcripts and worksheets that match the multimedia presentation. Take the quizzes for a quick measure of your progress and complete the chapter test to see if you may need to return to specific lessons.

### NES Middle Grades Math: Symmetry, Similarity & Congruence Objectives

There are four content domains in the NES Middle Grades Mathematics exam: this chapter falls under the Measurements and Geometry domain, which accounts for 25% of the test content. It relates especially to Objective 008, Euclidean geometry, which asks you to demonstrate an understanding of similarity and congruence, among other topics. There are 150 multiple-choice questions on the exam, which you have 4 hours and 15 minutes to complete. To pass the exam, you must score 220 on the 100-300 scaled score system.

The NES website has more information on testing centers and times. There, you will also register for the exam and retrieve your detailed score report a couple of weeks after the test. You will not have to wait that long to know if you passed, however, because they grade your exam at the testing center and provide your scaled score before you leave.
