Westcott Geodreieck Set Square 16 cm Transparent Polystyrene

The Westcott Geodreieck is a high-quality set square designed for precise technical drawing, geometry, and office use. Made from break-resistant transparent polystyrene, this 45-45-90 degree isosceles right triangle features a 16 cm hypotenuse and a beveled ink edge for clean, accurate lines. The zero point is centered on the hypotenuse, and the scale includes metric graduations in centimeters, millimeters, and degrees (0-180°). Parallel lines and an inner cut-out enhance functionality, making it ideal for students, architects, and professionals.

Advantages
