Celco 360 Degree Protractor 15cm Clear Plastic

A standard 180-degree protractor measures only half a circle and cannot directly measure reflex angles above 180 degrees. The Celco 360-degree protractor covers a full circle, so you can measure any angle - including reflex angles - in a single step without needing to calculate the remainder.

The dual scales let you read an angle from either the left or the right baseline without turning your page or the tool. The inner scale reads from right to left and the outer scale reads from left to right, making it straightforward to measure supplementary angles or work from either orientation.

This protractor is best suited to secondary school students and above, where the curriculum introduces reflex angles, geometry proofs, and technical drawing. Primary students working on basic angles up to 180 degrees may find a simpler semicircular protractor more appropriate.

The Celco 360-degree protractor is made from clear, rigid plastic. The transparency lets you see pencil lines and grid marks through the tool while measuring, which improves accuracy and reduces the need to re-mark reference points.

This listing is for a single protractor. If you need multiple units for a classroom set or bulk school purchase, please contact the Mega Office Supplies team to discuss quantity pricing options.
