Geometry set Strigo Zestaw geometryczny STRIGO — Strigo model 290989, school geometry tools kit

Strigo Zestaw geometryczny STRIGO is a compact school geometry tools kit designed for classroom and homework use. The set contains the basic instruments needed to draw and measure geometric figures: straightedges, a protractor for angle measurement, a compass for circles, and a ruler for length measurement. Components are sized and shaped for student hands and everyday study tasks, offering practical functionality in a portable arrangement.

Advantages

The kit provides a complete selection of essential drawing and measuring instruments in a single package, reducing the need to assemble tools from different sources. Components are made from durable, lightweight materials that balance rigidity with ease of handling. The compact layout and included protractor allow accurate construction of angles and circles, while the transparent elements of some pieces improve visibility of underlying markings for precise placement.

Suitable for

• School geometry classes and lessons
• Homework and study sessions requiring drawing of lines, angles and circles
• Basic drafting and technical drawing practice for students
• Measurement tasks in math lessons, including length and angle measurement

Key specifications

• Set composition: straightedge, protractor, compass, ruler and related accessories
• Materials: lightweight, impact-resistant plastics and metal for the compass parts
• Design: compact kit optimized for student use and storage
• Measurement scales: metric graduations on the ruler and straightedge
• Protractor range: 0–180° with degree markings for angle construction

How to use

Open the kit and remove the required instrument for the task. Use the straightedge or ruler for drawing straight lines and measuring distances by aligning the metric graduations with the marked points. Employ the protractor by placing its center point at the vertex and rotating to the desired degree marking to draw or measure an angle. Set the compass to the required radius using the ruler, anchor the point firmly on the drawing surface and rotate smoothly to draw circles or arcs. After use, clean any graphite or ink residue and store the instruments back in the kit to protect edges and tips.

Usage recommendations

For accurate results, use on a flat, stable surface and ensure pencil points are sharp and compass joints are tightened appropriately. Keep plastic components away from high heat and store the kit in a dry place. Replace worn compass leads and check measurement markings periodically for legibility to maintain precision during school tasks.
