Measuring angles with a circular protractor (Full video)

Khan Academy

Supporting grades: 4

Description: Lindsay measures angles with a circular protractor. So here we have this blue angle that we want to measure in degrees, and it's sitting on top of this circle. And those semicircle protractors measure from zero to 180 degrees. A full circle is better because an angle can measure up to 360 degrees.
