Practice lining up and reading a protractor while you measure a set of angles in this fun learning activity. The angles may range from 0° to 180°. The interactive protractor is already lined up with the vertex of each angle but you will have to rotate the protractor into proper position. The margin of error is only 1° and you must report measurement to the nearest whole number.
