45° Triangle Linex 2621GH Polystyrene Transparent Yellow 22.5 cm

The Linex 2621GH is a 45° triangle made of transparent yellow polystyrene with a side length of 22.5 cm and a thickness of 2 mm. It has a bevel and a plain edge, a 180° protractor scale in millimetres and a detachable handle. The zero point is located at the centre of the hypotenuse. Designed for precise drawing and measuring, the triangle is suitable for educational and professional geometry tasks.

Advantages

The transparent yellow polystyrene construction offers good visibility of the drawing surface while maintaining durability and light weight. The combined bevel and plain edges allow for varied line work and hatching, and the integrated 180° protractor with mm scale enables accurate angle measurement. The detachable handle improves grip and positioning without obstructing the working area.

Suitable for

• Teaching geometry and classroom exercises
• Technical and architectural drawing
• Measuring and marking angles up to 180°
• Hatching and drawing precise perpendiculars

How to use

Place the triangle on the drawing surface with the hypotenuse aligned to the reference line and use the 0 point at the hypotenuse centre to set angular measurements. Use the bevel or plain edge to draw fine or broad lines and hatchings. Read angles on the integrated 180° protractor with the mm scale. Attach the handle when additional grip or movement control is needed and remove it when it obstructs detailed work.

Usage recommendations

For precise results, use on a flat, stable surface and check alignment before drawing. Clean the polystyrene with a soft cloth to avoid scratches and store flat to prevent warping.
