Measuring angles using a protractor (Full video)

Khan Academy

Supporting grades: 4

Description: Learn to use a virtual protractor to measure angles. Created by Sal Khan. What I have right in front of me is the Khan Academy measuring angles exercise. And it's a pretty cool exercise because it has this little virtual protractor that we can use to actually measure angles. And I want to give credit to the person who built this protractor, because I think it's pretty neat.
