Ch 31: TACHS: Transformations in Math

About This Chapter

This chapter on transformations in math could be beneficial for students who want to brush up on the subject before they take the TACHS examination. Online video and text lessons can add to what your student has been learning in math class.

TACHS: Transformations in Math - Chapter Summary

When your eighth grade student utilizes these video and text lessons, they could learn to work with transformations in math. As they get ready for transformations questions on the TACHS examination's mathematics section, students can study how to solve translation problems, draw reflections, find distance and identify 2D shapes. While strengthening their understanding of the rules of rotation, students could become proficient at using coordinate notation and determining whether a rotation is clockwise or counter-clockwise. Studying the lessons could allow your child to:

  • Define and understand math rotations, reflections and translations
  • Understand the reflection of simple shapes and give examples of two-dimensional shapes
  • Recognize lines of symmetry
  • Graph translations, rotate shapes, find coordinates and graph reflections across the origin
  • Solve distance formulas
  • Use the Pythagorean theorem

Animated video lessons are followed by short quizzes that ensure that your student is absorbing information on translations. The lessons can be accessed online 24/7. Knowledgeable instructors provide their narration and expertise. Pause and play functions make navigating the lessons easy for students who are preparing to take the TACHS examination. There are also text transcripts and quizzes, and students can submit their questions when they go to the Dashboard area.

TACHS: Transformations in Math Chapter Objectives

Having supplemented their full-time school studies with this chapter's lessons, your student could be ready to address transformations questions when working on the TACHS examination's mathematics section. The test also includes questions that evaluate your child's language, reading and general reasoning abilities.

Registration materials can be picked up at Catholic schools, parishes, public libraries, and at public and private elementary schools. Admit Cards will then be dispersed, and they include pertinent test information. You and your child should choose three preferred Catholic high schools, and write them on the Admit Card. Bring the information and several No. 2 pencils to the testing appointment in November.

Rotations in Math: Definition & Overview

1. Rotations in Math: Definition & Overview

A geometric rotation refers to the rotating of a figure around a center of rotation. This lesson will get you going on rotations, give you some examples, and end with a quiz that tests your knowledge of rotations.

Reflections in Math: Definition & Overview

2. Reflections in Math: Definition & Overview

A reflection of an object is a 'flip' of that object across a line. This lesson will describe the basics of reflection, how to recognize one and how to create one.

What is Translation in Math? - Definition, Examples, & Terms

3. What is Translation in Math? - Definition, Examples, & Terms

In mathematics, translation refers to moving an object without changing it in any other way. This lesson will describe how to translate an object and give some examples. A quiz will follow to test your knowledge.

Reflecting Simple Shapes in a Mirror Line

4. Reflecting Simple Shapes in a Mirror Line

What is reflection? How can we reflect a shape over a line? You will learn about this as well as about the important properties of reflection as it relates to math!

What are 2D Shapes? - Definition & Examples

5. What are 2D Shapes? - Definition & Examples

In this lesson, you will find out how a flat piece of paper will help you determine what shapes are considered 2D. You will also learn the wide variety of 2D shapes you may encounter in life.

Identifying the Line of Symmetry: Definition & Examples

6. Identifying the Line of Symmetry: Definition & Examples

Symmetry can occur in many different ways in mathematics. In this lesson, learn how to identify unique forms of symmetry by finding the line of symmetry.

Graphing Translations & Finding a Set of Coordinates

7. Graphing Translations & Finding a Set of Coordinates

In this lesson, you're going to learn how to translate figures by counting boxes, find the coordinates of points, and learn how to translate a figure more quickly using simple math.

Rotating Shapes by Degrees, Center & Direction

8. Rotating Shapes by Degrees, Center & Direction

In this lesson, you're going to learn about the definition and basic concept of rotation as well as how to rotate any shape about the origin in a coordinate plane. Finish up the lesson, then test your understanding with a quiz!

How to Graph Reflections Across Axes, the Origin, and Line y=x

9. How to Graph Reflections Across Axes, the Origin, and Line y=x

A graph can be reflected in three ways - across the axes, the origin and the line y = x. There are specific rules to perform each reflection. This lesson will describe those rules and show you how to perform these reflections.

Distance Formulas: Calculations & Examples

10. Distance Formulas: Calculations & Examples

Let's go on a road trip! In this lesson, we'll practice calculations involving distance, rate and time. We'll also look at how we determine the relationship between distance and fuel.

Finding Distance with the Pythagorean Theorem

11. Finding Distance with the Pythagorean Theorem

How much faster is it to cut the corners in a race around the block? In this lesson, review the Pythagorean Theorem, and figure out how to solve without a right triangle.
