In this chapter, you'll learn the answers to questions including:
- What are line segments and rays, and how are they measured?
- How do the different types of angles compare to each other?
- How are angles and lines used in geometric constructions?
- What is the line segment bisection and midpoint theorem?
- How can line segments be divided into equal parts?
- How do transverse, parallel and perpendicular lines differ from each other?
- What steps are involved in constructing angle bisectors?
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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. What is a Ray in Geometry? - Definition & Examples
In this lesson, you'll learn what a ray is and see a few examples of rays. You'll also learn why we can't measure rays. Then, you can test your knowledge with a brief quiz.
10. Collinear Points in Geometry: Definition & Examples
In this lesson, you will learn the definition of collinear points in Geometry. Also, explore how collinear points relate to the real-world by looking at some examples.
11. Similar Figures: Definition & Examples
Similar figures show up quite often in the world around us. In this lesson, we will discuss similar figures and their properties. At the end of the lesson, you can test your knowledge with a quiz.
12. X-Coordinates: Definition & Examples
X-coordinates are an essential part of plotting points on graphs. Learn how an x-coordinate relates to direction on 2-dimensional mathematical grids. After, test yourself with the quiz.
13. What Are Congruent Figures? - Definition & Examples
In this lesson, you'll learn what congruent figures are. You'll also see a few examples of congruent and non-congruent figures. Then, test your knowledge with a brief quiz.
