Ch 24: SBA Math - Grade 8: Symmetry, Similarity & Congruence

About This Chapter

We can show your son or daughter the important information about symmetry, similarity and congruence so they will be well-prepared for the SBA Math Grade 8 Exam. This chapter consists of video lessons, transcripts and useful self-assessment quizzes.

SBA Math Grade 8: Symmetry, Similarity and Congruence - Chapter Summary

The lessons found in this chapter can help your child master the concepts and applications of symmetry, similarity and congruence before taking the SBA Math Grade 8 Exam. The videos go over all the important information, including:

  • Line of symmetry
  • Determining congruence and similarity in shapes
  • Lines in geometry: perpendicular, transverse and parallel
  • Recognizing parallel and perpendicular lines
  • Constructing perpendicular lines

Our experienced instructors carefully present the material to your child, explaining each aspect thoroughly and clearly. If a point needs clarifying, your child can access the experts for guidance through the interactive dashboard feature.

Objectives of the SBA Math Grade 8: Symmetry, Similarity and Congruence Chapter

The SBA Math Grade 8 Exam is a standardized exam administered in many states to determine if students are performing at grade level. The topics in this Symmetry, Similarity and Congruence chapter reflect the Concepts and Procedures objective, which contributes the majority of the test items. You and your child can get an idea of how well he or she knows the material when they take the self-assessment quizzes that accompany each video lesson. It also gives him the opportunity to practice answering questions like the ones on the exam.

Several types of questions comprise the SBA Math Grade 8 Exam. Most numerous are the multiple-choice items. These present a question or mathematics problem followed by several possible responses. More complex mathematical skills are measured via 'tasks', and the ability to solve real-world problems is measured via 'performance events'.

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.
