Set your protractor on the line drawn from the center of the circle to the left edge. (Line up the point in the middle of your
protractor to the point in the middle of the circle)

Continue above procedure, continually moving the protractor to the next line you drew, to draw the remaining pieces of the pie
graph. (Be careful – you may have an overlap or a gap when you are finished that is due to your rounding)
