Frequently Asked Questions

Q: What is included in the 6-piece full-circle protractor set?

A: The set includes 6 individual 360-degree full-circle protractors made from clear, transparent plastic. Each one features complete degree markings from 0° to 360°, making them ideal for geometry, technical drawing, and circle measurement tasks.

Q: How does a 360° full-circle protractor differ from a standard semicircle protractor?

A: A standard semicircle protractor only measures up to 180°, requiring you to reposition it for reflex angles. A 360° full-circle protractor covers the complete range of angles in a single placement, saving time and improving accuracy for geometric drawing and drafting work.

Q: Are these protractors suitable for both students and professional use?

A: Absolutely! The large, transparent design and clear degree markings make these protractors versatile enough for classroom geometry lessons, professional drafting, architectural sketching, and arts-and-crafts projects alike.

Q: What material are the protractors made from?

A: These protractors are crafted from durable, lightweight transparent plastic that allows you to see your drawing or diagram clearly through the tool while you work.
