Braille / Print Protractor
Bold large type numbers and braille dots mark the degrees along the half circle of this 180 degree protractor. Two braille dots mark 10 degree increments, while a single braille dot marks the 5 degree increments. An unusual feature of the protractor is the "wand." This is a long, flat piece which is pointed at one end and anchored on a pivot at the center of the protractor. When the pointed end of the wand is aligned with a certain degree measurement, the corresponding angle is created by the wand and the bottom edge of the protractor. Includes print and braille instructions.
