Ch 29: TACHS: Properties of Lines

About This Chapter

This chapter of the TACHS course reviews concepts related to lines and their properties as they will appear on the TACHS exam. Study the chapter's lessons and evaluate your knowledge with the short quizzes.

TACHS: Properties of Lines - Chapter Summary

Lines are the building blocks for shapes in geometry and will give way to angles, segments and intersections. This set of video lessons in the TACHS course will give you a study session that contains all of the information you need to know about lines to get ready for the TACHS exam. By completing this chapter, you will once again be familiar with the following topics:

  • Line segments, points, rays and angles
  • Tools for practicing geometric construction
  • The midpoint theorem and line segment bisection
  • Vertical, corresponding and alternate interior angles
  • Complementary and supplementary angles
  • Construction of an angle bisector
  • Constructing triangles, squares and hexagons

The video lessons all contain a timeline feature directly below the presentation, enabling you to conveniently jump back and forth and pick up where you left off if you need to step away from the course. If you get confused or need some extra help, you can use a feature in the dashboard to instantly contact a team of experts who can assist you with any questions you have about the properties of lines.

TACHS: Properties of Lines Objectives

The TACHS is your last stop on the way to a Catholic high school in one of New York City's five boroughs. Questions about properties of lines will appear on the Math section, and any questions you see will be presented in multiple-choice format.

Line Segments & Rays: Definition & Measurement

1. Line Segments & Rays: Definition & Measurement

Watch this video lesson to learn the difference between a line segment and a ray. You will also learn how to measure and add line segments. Learn why you can't measure or add a ray.

Points, Lines & Angles in Geometry

2. Points, Lines & Angles in Geometry

After watching this video lesson, you should understand the basic terms that form the foundation of geometry. Learn what a point is, what a line is, what an angle is, and learn about a special type of angle called a right angle.

Methods & Tools for Making Geometric Constructions

3. Methods & Tools for Making Geometric Constructions

Did you know that it's possible to do math without using numbers? This is exactly what Euclid did when he showed how to solve mathematical problems by drawing them out instead of with numbers.

Practice Making Geometric Constructions with Tools

4. Practice Making Geometric Constructions with Tools

There are a number of tools available to geometry students to help make their work a bit easier. In this lesson, we will review how to use many of them in order for you to get the most out of every geometry class.

Geometric Constructions Using Lines and Angles

5. Geometric Constructions Using Lines and Angles

Watch this video lesson to learn about geometric construction and how you can copy line segments and angles without using any numbers. All you need is a straight edge and a compass.

Line Segment Bisection & Midpoint Theorem: Geometric Construction

6. Line Segment Bisection & Midpoint Theorem: Geometric Construction

Watch this video lesson and you will learn how to bisect a line segment without measurements using just a compass and a straight edge. You'll also learn about the midpoint theorem, which lets you calculate the midpoint if you have the measurements.

Dividing Line Segments into Equal Parts: Geometric Construction

7. Dividing Line Segments into Equal Parts: Geometric Construction

Watch this video lesson to learn one way to easily divide any line segment into as many equal parts as you need. Also, learn where in real life this skill comes in handy.

Types of Angles: Vertical, Corresponding, Alternate Interior & Others

8. Types of Angles: Vertical, Corresponding, Alternate Interior & Others

In addition to basic right, acute, or obtuse angles, there are many other types of angles or angle relationships. In this lesson, we will learn to identify these angle relationships and discuss their measurements.

Complementary, Supplementary, Vertical & Adjacent Angles

9. Complementary, Supplementary, Vertical & Adjacent Angles

After watching this video lesson, you will know how to locate complementary, supplementary, vertical, and adjacent angles. You will understand how easy it is to visually see them. You will also know what to look for.

Constructing an Angle Bisector in Geometry

10. Constructing an Angle Bisector in Geometry

Watch this video lesson to learn a cool way to split an angle in half. You can use this method to split a pie slice in half where you can be sure each side is equal.

Constructing Equilateral Triangles, Squares, and Regular Hexagons Inscribed in Circles

11. Constructing Equilateral Triangles, Squares, and Regular Hexagons Inscribed in Circles

Constructing an accurate triangle, square, or hexagon within a circle is a matter of a few simple steps, and can be extremely practical. In this lesson, we'll practice the construction of those three shapes.
