1. Identifying Straight Angles
After viewing this lesson, you should know what a straight angle looks like. You should also know what a straight angle does and how you can identify one.
2. Angles of 90, 180, 270 & 360 Degrees
Angles make up the physical structures all around us, from street corners and traffic signs, to buildings, to the chair you're sitting on right now. In this lesson, we will explore the key angles of 90, 180, 270, and 360 degrees as they appear in mathematics and in the structures around us.
3. How to Measure Angles with a Protractor
You're surrounded by angles at home, at school, and even when you're walking down the street. In this lesson, you'll learn how to measure different angles using a protractor.
4. Working with Adjacent Angles
After watching this video lesson, you will know how to work with adjacent angles. You will know how to identify them, how to find the sum of the adjacent angles and how to find the measure of a missing angle.
