The Round D Protractor covers a complete turn rather than stopping at the 180-degree limit of a semicircular tool. Its degree markings continue around the full outer ring, making it useful for reflex angles, bearings, rotations and circular geometry exercises.

A translucent amber body carries number sequences around the perimeter. The broad central crossbar provides a straight reference through the middle, while the open sections reduce visual obstruction over a page or drawing sheet.

Students can use the 0-360 scale for topics where direction matters, such as clockwise rotation or an angle larger than a straight line. It also provides the familiar 90, 180 and 270-degree quarter-turn references within one continuous circle.

Each Rs. 135 order includes one Round D 360 Degree Protractor. It is a separate full-circle option for buyers whose exercise cannot be completed with the 0-180 degree D Half models.
