Ch 28: TACHS: Symmetry, Similarity & Congruence

About This Chapter

Your child can build upon what they have learned about symmetry, similarity and congruence by studying this chapter's lessons, which delve into these topics. This chapter can help prepare your student for the TACHS examination's math questions.

TACHS: Symmetry, Similarity and Congruence - Chapter Summary

Working through this chapter could solidify your child's understanding of the symmetry, similarity and congruence of geometric shapes. Presented in an online format, its informational video lessons review steps to recognize and construct different kinds of lines and shapes. Coplanar lines, opposite reciprocals and lines of symmetry are some of the terms your eighth-grade student can review while preparing for the TACHS examination. This chapter could contribute to his or her ability to:

  • Locate the line of symmetry in shapes
  • Know when shapes are congruent or similar
  • Recognize transverse, parallel and perpendicular lines in geometric shapes and real-life objects
  • Draw perpendicular lines with a compass
  • Identify perpendicular lines within squares, rectangles and other shapes

All of the online lessons are related, and they can increase your student's knowledge of symmetry, similarity and congruence. Real-life instructors deliver the lessons, and experts can provide answers to submitted questions. As your student gets ready for the TACHS examination, he or she can pause the videos in order to take notes or use the video tags to find pertinent information. Quizzes are included in each lesson, and they usually consist of about five questions. These short tests can also be taken more than once. When the answers are correct, students can print out the results for easy referral later.

TACHS: Symmetry, Similarity and Congruence Chapter Objectives

The TACHS examination will not only test your child's knowledge of mathematics topics such as symmetry, similarity and congruence, but it will also assess their reasoning, language and reading abilities. Register your student in one of three ways. Internet registration with a credit card is the preferred method. However, you can register by calling or mailing an application along with your cashier's check or money order.
