Measuring angles

Now that you know what angles are, you're ready to start measuring them! The tool we use is called a "protractor", and in this lesson we'll review how to use it, and how to read the numbers on a protractor to measure any angle. You'll get some practice both creating angles, and also measuring some of the many angles you can find in the real world. Ready? Set. Go Measure!
