About This Chapter
Lines and Angles in Geometry - Chapter Summary and Learning Objectives
Parallel and perpendicular lines, as well as angles, all follow exact geometric principles. Our instructors provide video lessons that are around 5 minutes long to guide you through focused segments of geometric angle concepts to ensure you can make sense of lines and angles in geometry. We provide tools to enhance your user experience, such as video transcripts and the ability to ask the instructor a question. The lessons help you understand the following:
- Parallel, perpendicular and transverse lines
- Line segments and rays
- Different types of angles
|Line Segments & Rays: Definition & Measurement||Discover the difference between a line segment and a ray.|
|Types of Angles: Right, Straight, Acute & Obtuse||Summarize information about the right, acute and obtuse angle and also the straight line.|
|Complementary, Supplementary, Vertical & Adjacent Angles||Recall what angles add up to 90 degrees and angles that add up to 180 degrees.|
|Types of Angles: Vertical, Corresponding, Alternate Interior & Others||Discuss angles beyond the most basic angle types.|
|Parallel, Perpendicular and Transverse Lines||Demonstrate the differences between parallel, perpendicular and transverse lines|
1. Types of Angles: Right, Straight, Acute & Obtuse
Angles are everywhere. Learn about the different types of angles we use in mathematics, including right angles, acute angles, obtuse angles, and straight angles. See if you can tell the difference with a quiz.
2. 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.
3. 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.
