Answer

A protractor is used to measure the number of degrees in a sector. First, you must draw a line from the center of the circle to the left edge. Next, place the hole of the protractor over the center of the circle, making sure that the 0 on the protractor is on the line. Finally, make a mark at the desired number of degrees. This gives you the size of the sector.
