Geometry set Cricco model 331721 — 4-piece drawing set (compass, divider, ruler, protractor)

Cricco model 331721 is a 4-piece geometry set designed for basic drawing, angle measurement and distance transfer in school and study environments. The set contains a compass for drawing circles, a divider for transferring measurements, a straight ruler for drawing and measuring lengths, and a protractor for measuring and constructing angles. The components are arranged to cover typical school tasks in geometry and technical drawing while remaining compact and easy to store.

Advantages

The set provides the fundamental tools needed for classroom geometry in a single compact kit, making it convenient to carry and store. Each tool is built for straightforward use: the compass allows stable circle drawing, the divider helps transfer distances accurately, the ruler gives clear measurement markings, and the protractor enables precise angle reading. The component selection supports a range of basic drafting and measuring tasks without unnecessary complexity.

Suitable for

• School geometry lessons and classroom exercises
• Homework and study sessions requiring drawing or measuring
• Basic technical drawing and simple drafting tasks
• Measuring and transferring distances in educational projects

Key specifications

• Set composition: compass, divider, straight ruler, protractor
• Ruler length: standard student size suitable for notebooks and school desks
• Protractor: semicircular with degree markings for angle measurement
• Compass: adjustable for various circle radii, with a screw or hinge adjustment mechanism
• Divider: pointed tips for accurate distance transfer on paper
• Material: lightweight construction suitable for everyday school use

How to use

Use the compass to draw circles and arcs by fixing one leg at the center point and rotating the other leg with the pencil lead. Adjust the compass span to set the desired radius. Use the divider to copy or transfer distances between points on a drawing by setting the points to the required separation and marking positions. Place the ruler along the intended line to draw straight segments and read linear measurements using the scale. Align the protractor with a baseline to measure or construct angles by reading degree markings. Take care to use a sharp pencil for clear lines and to secure paper to the desk for greater stability.

Usage recommendations

For durable and accurate results, periodically check and tighten adjustable joints on the compass and divider, replace pencil leads as needed, and store the set in a protective case or sleeve to prevent bending or damage to tips and edges.
