Ch 34: TACHS: The Pythagorean Theorem

About This Chapter

The Pythagorean theorem and its applications are the focus of this chapter. Our series of online video lessons outline this math concept for the benefit of eighth-grade students who want to do well on the TACHS examination's mathematics section.

TACHS: The Pythagorean Theorem - Chapter Summary

Here's an opportunity for your student to study the Pythagorean theorem and its purpose in mathematics. In advance of answering relevant questions on the TACHS examination, a young learner can explore the theorem's basics through the online videos in this chapter. Your student could become proficient at applying the Pythagorean theorem to identify and find the missing sides of right triangles. Practice problems are provided so that your child can build skills in this area. Upon completion of the lessons, your student might be able to:

  • Use the Pythagorean theorem to find the answers to problems
  • Understand the converse of the Pythagorean theorem
  • Determine the length of a right triangle's hypotenuse
  • Locate a right triangle's shorter sides
  • Calculate the answers to functional problems

Before your child takes the TACHS examination, he or she can use these teacher-delivered video lessons to brush up on the Pythagorean theorem and build upon what has already been covered in their math class. Designed to be self-paced, the animated video lessons feature stop, forward and pause functions, and they can be watched online with a desktop computer, laptop or tablet. Main topics can be reached quickly by using the video tags under the timeline link. Multiple-choice quizzes evaluate your eighth-grader's progress. Quiz results can be printed and used to study conveniently offline.

TACHS: The Pythagorean Theorem Chapter Objectives

There are four sections on the TACHS examination: Reading, Language, Mathematics and Ability. Your child can apply what they learned about the Pythagorean theorem during the Mathematics section. Registration can be completed online, by phone or by mail.

The Pythagorean Theorem: Practice and Application

1. The Pythagorean Theorem: Practice and Application

The Pythagorean theorem is one of the most famous geometric theorems. Written by the Greek mathematician Pythagoras, this theorem makes it possible to find a missing side length of a right triangle. Learn more about the famous theorem here and test your understanding with a quiz.

The Pythagorean Theorem: Converse and Special Cases

2. The Pythagorean Theorem: Converse and Special Cases

The Pythagorean Theorem is a famous theorem for right triangles. Watch this video to learn how the Pythagorean Theorem relates to the law of cosines and how the converse of the Pythagorean Theorem can help you identify right triangles.

How to Find the Hypotenuse of a Right Triangle Using the Pythagorean Theorem

3. How to Find the Hypotenuse of a Right Triangle Using the Pythagorean Theorem

After watching this video lesson, you will be able to use the Pythagorean Theorem and its resultant formula to help you find the length of the hypotenuse of a right triangle when you know the measurements of the triangle's two other sides.

How to Find Shorter Sides on a Right Triangle Using the Pythagorean Theorem

4. How to Find Shorter Sides on a Right Triangle Using the Pythagorean Theorem

Sure, the Pythagorean Theorem is useful for finding the hypotenuse of a right triangle, but what about the other sides? As this lesson shows, it's just a matter of flipping the formula.

How to Solve Functional Problems Involving the Pythagorean Theorem

5. How to Solve Functional Problems Involving the Pythagorean Theorem

One of the most useful aspects of studying triangles is the Pythagorean Theorem. In this lesson, we use it to find the unknown length of a side of a triangle, whether it is a shorter side or the hypotenuse.
